The answer is b
The way I do it is the area of the front back times 2 which is 2x4x2=16
Then top and bottom times 2 which is 4x8x2=64
Then left and right which is 2x8x2=32 then you add them all together so 16+64+32=112
Hope this helped :)
Using the z-distribution, we have that:
- The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.
- The <u>margin of error</u> is of 0.8 in.
- The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.
The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the <u>sum of all observations divided by the number of observations</u>. Hence:

The margin of error of a z-confidence interval is given by:
In which:
- z is the critical value.
is the population standard deviation.
- n is the sample size.
We have to find the critical value, which is z with a p-value of
, in which
is the confidence level.
In this problem,
, thus, z with a p-value of
, which means that it is z = 2.575.
Then, the margin of error is:



The <u>margin of error</u> is of 0.8 in.
The interval is:



The interpretation is:
Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

Solving for the missing variable
More than means addition
lets call our number 'x'
is means the equal sign
so we would get
x + 4 = 12
