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 than women. Set alpha at .05.
Would your decision have been different if alpha were set at .01?
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?
How does hypothesis testing help support the fields of criminology or criminal justice science as sciences that employ the scientific method? Give two specific examples based from peer reviewed literature.
