(Hypothetical) The General Social Survey measures the amount of hours that individuals spend on the internet each week. Males use the Internet 10.17 hours per week. (standard deviation 11.71 N = 118), while women use the Internet 9.08 hours per week (standard deviation 12.26; N = 157).

Test the research hypothesis that men use the internet more hours a than women. Set alpha at .05.

Would your decision have been different if alpha were set at .01?

(Hypothetical) Is there a significant difference in the level of community service participation between criminal justice majors and accounting majors?

What is your research hypothesis? Should you conduct a one tailed or a two tailed test? Why?

Your study finds that 38% of 160 criminal justice majors reported volunteering in the previous month, compared with 29% of 210 accounting majors.

Present the five-step model, testing your hypothesis at the .05 level. What do you conclude?
