a. Would you expect that TV watching has a normal distribution? Why or why not?
b. On what assumptions is the confidence interval shown based? Are any of them violated here? If so, is the reported confidence interval invalid? Explain.
c. What’s wrong with the interpretation, “In the long run, 95% of the time females watched between 2.88 and 3.28 hours of TV a day.”
