Explanation:
Domino's pizza claims that its mean delivery time has a mean of at most 30 minutes. A random selection of 16 delivery times was found to have a mean of 28.5 minutes and a standard deviation of 3.5 minutes.
a) What assumption(s) do you need to conduct a hypothesis testing on this problem?
b) Assume this assumption(s) in (a) is satisfied, and check if there is enough evidence to support their claim at the 0.01 level of significance.
Answer:
a) Check Explanation
b) The p-value obtained is greater than the significance level at which the test was performed, hence, there isn't enough evidence to support the claim and conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.
Explanation:
a) The assumptions required to conduct a suitable t-test about a mean include
- The data must be obtained from a random sample of the whole population (simple random sample).
- Individual sample data values are expected to be independent of one another.
- The sampling distribution should be normal or approximately normal.
b) For hypothesis testing, the first thing to define is the null and alternative hypothesis.
The null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test.
While, the alternative hypothesis usually confirms the the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test.
For this question, we want to investigate if the mean delivery time for the Domino's Pizza is truly less than 30 minutes.
Hence, the null hypothesis is that there isn't enough evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes. That is, the mean delivery time for Domino's Pizza is greater than 30 minutes.
The alternative hypothesis will now be that there is significant evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.
Mathematically,
The null hypothesis is given as
H₀: μ ≥ 30 minutes
The alternative hypothesis is given as
Hₐ: μ < 30 minutes
To do this test, we will use the t-distribution because no information on the population standard deviation is known
So, we compute the t-test statistic
t = (x - μ)/σₓ
x = sample mean = 28.5 minutes
μ₀ = The standard we are comparing against = 30 minutes
σₓ = standard error = [σ/√n]
σ = Sample standard deviation = 3.5 minutes
where n = Sample size = 16
σₓ = [3.5/√16] = 0.875
t = (28.5 - 30) ÷ 0.875
t = -1.71
checking the tables for the p-value of this t-statistic
Degree of freedom = df = n - 1 = 16 - 1 = 15
Significance level = 0.01
The hypothesis test uses a one-tailed condition because we're testing only in one direction.
p-value (for t = -1.71, at 0.01 significance level, df = 15, with a one tailed condition) = 0.053932
The interpretation of p-values is that
When the (p-value > significance level), we fail to reject the null hypothesis and when the (p-value < significance level), we reject the null hypothesis and accept the alternative hypothesis.
So, for this question, significance level = 0.01
p-value = 0.053932
0.053932 > 0.01
Hence,
p-value > significance level
This means that we fail to reject the null hypothesis & say that there isn't enough evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.

What banks have a fixed mortgage rate?
Answer:
First Bank has fixed mortgage for now
Most banks offer fixed-rate mortgages. These types of loans maintain the same interest rate throughout the life of the loan, unlike adjustable-rate mortgages which fluctuate with market interest rates.
Explanation:Most banks and financial institutions offer fixed-rate mortgages to their clients. A fixed-rate mortgage has the same interest rate for the entire term of the loan which could be 15 or 30 years. Unlike an adjustable-rate mortgage, a fixed-rate mortgage does not fluctuate with changes in market interest rates.
If inflation falls unexpectedly by 3%, the effect on a homeowner with a fixed-rate mortgage would be nonexistent in terms of their mortgage repayment because the interest rate would not change. However, if a homeowner has an adjustable-rate mortgage, their rate should theoretically fall by the same amount as inflation to maintain the real interest rate.

Answer: demands is higher than supply & $200
Answer:
Higher than retail price because: demand is higher than supply
You would have saved: $200
Explanation:
The amount of money that would be saved in six months because the demand exceeds the supply would be:
- $ 200
Given that, the sale price(advertisement price) of a gaming system exceeds its retail price which implies that the demand exceeds the supply. Therefore, if one wishes to wait for six months, he/she could save $200 because the price would eventually get lower to come to the equilibrium price.

On your own, locate three reputable sources on the causes of the 2008 financial crisis. At least one such source should be a primary source. To ensure your sources are reputable, follow these guidelines when searching: The source clearly identifies who the author is. The source's author has expertise in the field in which the person is writing. For instance, if you are reading a source on an environmental issue, you would want the author to be someone who has research experience with the topic. The source is academic, meaning it is published by a respected site or source in the field of study, such as official government Web sites a university, academic journals, or reputable news sources. The source does not state opinions as facts. The source clearly cites where its information came from. The source is current and does not include dated information. Analyze each source, and organize your argument in chronological order. By arranging your reasoning in sequential order, you present a timeline of the various causes of the financial crisis in 2008. Finally, you will compare the information from your secondary sources with the information given in your primary sources. In the second half of your essay, evaluate the explanations for actions or events that occurred during the financial crises. Do your sources have differing points of view or different conclusions? Consider and explain which sources are more correct, based on your analysis. Prompt Your writing should be in complete, complex sentences and no less than 500 words in length. The financial crisis is a complex topic; be sure to prove your understanding of key economic terms and policies that contributed to the crisis. You will also need to cite the three sources you use to find information on the financial crisis. Rubric
To analyze the 2008 financial crisis, one must use a variety of reputable sources, apply the CRAAP test for evaluation, and compare primary and secondary sources to present a well-reasoned chronological narrative.
To understand the causes of the 2008 financial crisis, one must conduct thorough research and analyze information from reputable sources. Evaluating sources involves using the CRAAP test, assessing its currency, reliability, authority, accuracy, and purpose. When researching such an intricate topic as the financial crisis, reliability and expertise of authors and the credibility of the sources become pivotal. It's important to ensure the authors have expertise in the field and the publications are respected within academia or reputable media outlets.
To construct a well-founded argument, one should analyze sources through a critical lens, comparing and contrasting information from both primary and secondary sources. Primary sources might include official reports, financial data, or firsthand accounts from the time, whereas secondary sources could be scholarly articles or analyses that interpret primary data. Seeking out various perspectives and cross-referencing information help achieve a more balanced understanding. Academic writing should not only recount facts but also synthesize information to present a coherent narrative. Organizing the researched material in a chronological manner can help build a timeline of events that led to the crisis, from the rise of subprime lending to the eventual downfall of major financial institutions. Finally, comparing differing viewpoints and conclusions from various sources helps to establish which narratives are most supported by the evidence.

True or False: The customer experience begins the moment the customer enters the door
The customer experience begins the moment the customer enters the door and continues throughout their entire journey with the business.
Explanation:The statement is true: the customer experience begins the moment the customer enters the door. This is especially important in the business context as it sets the tone for the entire interaction between the customer and the business. From the moment they enter, customers start forming opinions and judgments based on their initial impressions.
For example, in a retail store, the layout, cleanliness, and ambiance of the store can greatly impact the customer's experience. A well-designed store with friendly staff can make the customer feel welcome and encourage them to explore the products. On the other hand, a poorly maintained store or unfriendly staff can create a negative experience.
Moreover, the customer's experience continues throughout their entire journey with the business, including interactions with the staff, the quality of the product or service, and the level of customer support provided. All these factors contribute to shaping the overall customer experience.

tiers are advertised for the same grades of gasoline. Gasoline purchased with cash is 20 cents per gallon less than gasoline purchase with a credit card.
Why would the gas station charge more for purchases made with a credit card?
To offset processing fees charged by credit card companies
To protect credit card users from ID theft
To bring in more customers
To discourage the use of credit cards
Answer:
Could be the first and the last, if you are to choose more than one. If only one, I would choose the last one.
Explanation:
Answer:
It would be "To offset processing fees charged by credit card companies".
Explanation:
It wouldn't make sense to protect credit card users from ID theft, since that is taken care of at the credit card company's level.
This specific discount wouldn't necessarily bring in more customers since half the demographic is probably either cash or credit card anyway.
Lastly, credit card companies due charge fees for the use of credits cards, so a company would use this tactic out of fairness for it's customers and the profit of the business.

True or False - Taxation is the most obvious disruption to the circular flow free market model.
Taxation is a fundamental component of modern economies and serves several purposes, such as funding government services, redistributing income and wealth, and addressing externalities. Hence the statemnet is true .
Why Taxation is the most obvious disruption to the circular flow free market model ?However, taxation does disrupt the circular flow free market model by taking a portion of individuals' income and reducing the amount of money they have available to spend on goods and services. This, in turn, affects the demand for goods and services, as well as the level of economic activity.
Moreover, taxation can also distort the incentives of individuals and businesses. For example, high taxes on certain goods may discourage people from buying them, while tax breaks for specific industries or activities may encourage investment in those areas, regardless of their economic viability.
