The 2010 General Social Survey contains information on the number of hours worked by a respondent each

The 2010 General Social Survey contains information on the number of hours worked by a respondent each week. The mean number of hours worked per week is 45.27, with a standard deviation of 15.31. The sample size is 196.

1. Using this data, provide a hypothetical numerical example which demonstrates that the precision of a confidence interval is in part a function of sample size

2. Using this data, provide a hypothetical numerical example which demonstrates that the precision of a confidence interval is a function of both sample size and the level of confidence

The GSS 2012 measures the amount of hours individuals spend on the Internet per week. Men use the Internet 18.67 hours per week (standard deviation = 10.66, N = 127), while women use the Internet 12.28 hours per week (standard deviation = 14.26, N = 182). Please review formulas 8.5 and 8.6 on page 217 to complete this problem set.

3. Test the research hypothesis that men use the Internet more hours than women, set alpha at .05

4. Would your decision have been different if alpha were set at .01 (1 pt)?
