a. Set up the hypotheses of a significance test to analyze whether the population means differ for females and males.

b. Using software (such as MINITAB) in which you can use summarized data, conduct all parts of the significance test. Interpret the P-value, and report the conclusion for a significance level of 0.05.

c. If you were to construct a 95% confidence interval comparing the means, would it contain 0? Answer based on the result of part b, without actually finding the interval.

d. Do you think that the distribution of TV watching is approximately normal? Why or why not? Does this affect the validity of your inferences? What assumptions do the methods make?
