Question
As practiced by many in buying skirts or pants, they use the neckline to check if the waistline of the skirts or pants fits them. We would like to study this claim by using a random sample of neckline.
The data collected are summarized as follows:

For ALL computations, do not use rounded values in your calculation. Try to use as much information
(include as many digits after the decimal point) as you can from previously computed values.
For ALL computations, if the answer is not a whole number, round off to the nearest hundredths.
