Experiment 2:

Shoe sizes are collected from a random sample of 8 fathers and their adult sons to determine if the mean shoe size for fathers is significantly smaller than the average shoe size of the sons.  It can be assumed that the shoes sizes of both the fathers and the sons are normally distributed.

Is the sample independent or dependent? What is the null and alternative hypothesis?
