The correct answer is option (C) Standard Deviation.The estimator that consistently has a skewed sampling distribution is the standard deviation, especially when the original data is non-symmetric or skewed.
Among the given options, the estimator that will consistently have a skewed sampling distribution is the standard deviation. When estimating the standard deviation from a sample, the resulting distribution does not always follow a normal pattern, especially if the original data is skewed. The standard deviation is calculated using each data point's deviation from the mean, which can lead to skewed results in non-symmetric distributions.
For instance, in a skewed distribution with extreme values, the mean and subsequently the standard deviation can be disproportionately influenced by those extremities, hence failing to accurately reflect the spread of the majority of the data. Therefore, sometimes measures like the median, which is not as sensitive to outliers, are considered better representations of the central tendency in a skewed data set.
Additionally, the standard deviation is meaningful for symmetrical distributions, while skewed distributions require a consideration of other measures such as the modes, medians, or quartiles. When presented with data, always visualize it using a histogram or a box plot to better understand the distribution.

What is the value of the product (3 – 21)(3 + 2/)?
5
9 + 4
9 - 41
13
The product of (3 – 2i) and (3 + 2i) simplifies to 13 after expanding and simplifying the expression, canceling out the imaginary terms.
To find the product of (3 – 2i) and (3 + 2i), we'll use the distributive property:
(3 - 2i)(3 + 2i) = 3(3) + 3(2i) - 2i(3) - 2i(2i)
= 9 + 6i - 6i - 4i²
Since i² = -1, substitute -1 for i²:
= 9 + 6i - 6i - 4(-1)
= 9 + 6i - 6i + 4
The terms with imaginary parts cancel out:
= 9 + 4
= 13
Thus, the product of (3 – 2i) and (3 + 2i) equals 13.

What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including basic arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
Given that the Data point is corrected from 11.1 to 11.7. As we already know if we increase the value of the data point the mean will rise when a data point is added that is above the mean or subtracted that is below the mean. The mean will drop if one or more data points are removed that are above the mean or added that are below the mean.
Therefore, If data point 1.1 is corrected to 11.7 then the mean will increase and the data set has two modes.

The map shows the length (in miles) of shoreline along the Gulf of Mexica for each state that borders the body of water. What is the probability that a ship coming ashore at a random point in the Gulf of Mexico lands in the given state? Round your answers to the nearest whole percent.
Answer:
TX- 23%
AL- 3%
FL- 47%
LA- 24%
MS- 3%
Step-by-step explanation:
Final answer:
To find the probability of a ship coming ashore in a given state, divide the length of its shoreline by the total length of the Gulf of Mexico's shoreline.
Explanation:
To find the probability of a ship coming ashore at a random point in the Gulf of Mexico landing in a given state, we need to divide the length of the shoreline of that state by the total length of the Gulf of Mexico's shoreline. Let's assume there are 4 states that border the Gulf of Mexico: State A with 100 miles of shoreline, State B with 150 miles, State C with 200 miles, and State D with 250 miles. The total shoreline length of the Gulf of Mexico would be 700 miles (100 + 150 + 200 + 250).
Now, we can find the probability for each state by dividing its shoreline length by the total shoreline length. For example, for State A, the probability would be 100/700 which is approximately 0.1429 or 14.29%.
Following the same calculation, the probability for State B is 150/700 which is approximately 0.2143 or 21.43%, the probability for State C is 200/700 which is approximately 0.2857 or 28.57%, and the probability for State D is 250/700 which is approximately 0.3571 or 35.71%.
alice took out 80/20 mortgage on a $232,000 home. what is the amount financed under the first mortgage?
Answer:
The amount financed under this mortgage is $185,600
Step-by-step explanation:
Alice took out an 80/20 mortgage on a $232,000 home.
80/20 mortgage means pay 20% down payment and 80% finance amount of home value.
Home value = $232,000
Now, we need to find finance amount from this hone value of $232,000
Let's calculate the 80% of $232,000 as finance amount;
Finance amount = 80% of 232000
Finance amount = 0.80 x 232000
Finance amount = 185,600
Hence, The amount financed under this mortgage is $185,600

Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.
α = 0.08; H1 is μ ≠ 3.24
a. ±1.75
b. 1.75
c. ±1.41
d. 1.41
Answer:
The critical z value used to test a null hypothesis is ±1.75.
Step-by-step explanation:
We are given that the data has a normal distribution and the number of observations is greater than fifty.
Also, the hypothesis given to us is;
Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 3.24
Alternate Hypothesis, [tex]H_1[/tex] : [tex]\mu\neq[/tex] 3.24
This means that our test is two-tailed because in the alternate hypothesis we are concerned with mean value is less than or greater than 3.24.
Also, level of significance (α) = 0.08
Now, for two-tailed test level of significance becomes = [tex]\frac{\alpha}{2} =\frac{0.08}{2}[/tex] = 0.04
So, in the z-table the critical value of x at 4% significance level is given as 1.75.
Since, this is two-tailed test so the critical z value used to test a null hypothesis would be ±1.75.
At the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75. and this can be determined by using the given data.
Given :
Assume that the data has a normal distribution and the number of observations is greater than fifty.α = 0.08H1 is μ ≠ 3.24According to the hypothesis test:
Null Hypothesis -- [tex]\rm H_0:\mu=3.24[/tex]
Alternate Hypothesis -- [tex]\rm H_1 : \mu\neq 3.24[/tex]
According to the given data, the significance level is given by α = 0.08. So, the significance level for the two tailed test is given by:
[tex]\rm \dfrac{\alpha }{2}=\dfrac{0.08}{2}=0.04[/tex]
So, for the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75.
So, the correct option is a).

A tourist on vacation went scuba diving at a depth where 0.0871 l of gas in his blood is under 12.0 atm of pressure if he instantly boards a plane where his blood will be under 1.50 atm of pressure what will be the volume of gas in his blood
Answer:
0.6968 L
Step-by-step explanation:
We can calculate the resulting volume thanks to Boyle's Law, which tells us The volume is inversely proportional to the pressure:
• If the pressure increases, the volume decreases.
• If the pressure decreases, the volume increases.
Thus:
P1V1 = P2V2
We know that P1 = 12 atm, V1 = 0.0871 L and P2 = 1.5 atm, that is, the value that we do not know about V2, therefore we solve for V2:
V2 = P1V1 / P2
Replacing:
V2 = 12 * 0.0871 /1.5
V2 = 0.6968 L
Which makes sense, since decreasing the pressure increases the volume.

The area of a rectangle is 344 square inches. If the rectangle is 16 inches wide, find the perimeter of the rectangle.
A. 67 inches
B. 72 inches
C. 75 inches
D. 80 inches
Answer:
C. 75 inches
Step-by-step explanation:
well if it's a rectangle then we would do A = L x W we are told the Width and the Area
344 = L x 16
344 / 16 = 21.5
P = L + L + W + W
16 + 16 + 21.5 + 21.5
16 + 16 = 32
21.5 + 21.5 = 43
32 + 43 = 75
the perimeter is 75 inches
Final answer:
To find the perimeter of the rectangle, we calculate the length by dividing the area by the width and then apply the perimeter formula. We find that the length is 21.5 inches and the perimeter is 75 inches.
Explanation:
To find the perimeter of the rectangle when the area is 344 square inches and the width is 16 inches, we need to use the area formula of a rectangle, which is Area = length × width. Since we have the area and the width, we can calculate the length:
Divide the area by the width to find the length: Length = 344 sq in / 16 in = 21.5 in.
Now, use the perimeter formula: Perimeter = 2 × (length + width).
Substitute the length and width into the formula: Perimeter = 2 × (21.5 in + 16 in) = 2 × 37.5 in = 75 inches.
The correct answer is C. 75 inches.
