In the 2016 General Social Survey, subjects reported the time spent every day watching television. Men reported watching an average of 5.3 hours per day and women reported watching an average of 4.1 hours per day. The difference in means is 1.2 and the associated standard error of the difference is .191. (a) If you hypothesize that men and women’s average amount of television per day differs significantly, set up the null and alternative hypotheses for a significance test. (b) Construct the 90% confidence interval for the difference between the means in men and women (critical value is 1.64). (c) Construct the 95% confidence interval for the difference between the means in men and women (critical value is 1.96).

1. One hundred eight Americans were surveyed to determine the number of hours they spent watching television each month. The average time was 75 hours a month (that’s approximately 2.5 hours per day). In the population of all Americans, it is estimated that the variation of the time spent watching television per month is 15.2 hours. Use this information to construct a 98% confidence interval to estimate the average time spent watching television per month for all Americans. A) 71.592...
