(b) Find the critical value(s) and identify the rejection region.

A sociologist claims that children spent more time watching television in 1981 than children do today. A study was conducted in 1981 to find the time that children
watched television on weekdays. Recently, a similar study was conducted. The results of these studies (in hours per weekday) are shown below. Assume the
population standard deviation is 0.6 for 1981 and 0.7 for today. At a
=0.05, can you support the sociologist's claim? Complete parts (a) through (d) below.
