peter surveyed a random sample of adults and a random sample of teenagers about the number of hours that they exercise in a typical week. What comparative inference can Peter make from the data sets?

Step-by-step explanation:

Hello!

Peter is interested in comparing the number of hours adults and teenagers exercise per week, for this selected one random group of adults and a random group of teenagers and surveyed them on their weekly exercise times.

To compare the weekly exercise time of both populations, the best is to use a measure central tendency, so you can compare their positions and see if they are significantly similar or not.

The most common parameters to use for comparing two populations are its population means. So the analysis to do is a two independent sample test.

I hope this helps!

where r is the radius of the pizza.
