Due: Friday October 22 5:00pm S = 1,47 The General Social Survey asks respondents about the "number of hours of TV watched per day (values are actual numbers of hours)." For the table given below, I have calculated the mean (X) and standard deviation (s), like you did in Assignment 4. Next, let's assume that this sample's mean and standard deviation match the population parameters (i.e., population mean and standard deviation of the population) for TV watching in the U.S. 1) Compute the z score for each of the following 12 cases, i.e., use the mean and standard deviation for the sample of 12 cases (N=12) to transform Xi to Zi for each case. Remember to report to two places to the right of the decimal. Then 2) find the area (and report as a percent) for each of the questions below using your Appendix A. Remember to report the percent to two places to the right of the decimal. Helpful suggestion: draw the normal curve and then mark out the area you are trying to find as shown in our Week 8 and 9 slides and videos.
