Answer #1

B. ​Two-Sample T-Test

Explanation:

For the given scenario we have to check the claim whether people send less text messages as they get older.

For this scenario, we can collect two random samples with ages less than or equal to 30 and ages more than 30. Then we can find the find the sample statistics for both samples and we can use two samples t test for checking whether the group with younger people send more messages than the group of older people or not.

Which hypothesis test do I use for this statement? It is believed that the blue team is 3 inches taller than the red team. (for my data, in one column i have their heights and team color in another column) For my null and alternative hypothesis, how do I find those? I was thinking take the difference of the means since we are testing whether one team is 3 inches taller? For example, null is u1-u2= 0, alternative is u1-u2=...
