Results on seat belt usage from the 2003 Youth Risk Behavior Survey were published in a USA Snapshot on January 13, 2005. The following table outlines the results from the high school students who were surveyed in the state of Nebraska. They were asked whether or not they rarely or never wear seat belts when riding in someone else's car. Using α = .05, does this sample present sufficient evidence to reject the hypothesis that gender is independent of seat belt usage?

	Female	Male
Rarely or never use seat belt	203	311
Uses seat belt	1246	1174

Decision:

P-value is less than significance level (0.05 ), there we reject the null hypothesis(Ho).

Conclusion :

Yes , There is sufficient evidence to reject the hypothesis that gender is independent of seat belt usage .

In the summer of 2003, The New England Journal of Medicine published results of some Scandinavian research. Men diagnosed with prostate cancer were randomly assigned to either undergo surgery or not. Among the 347 men who had surgery (group 1), 16 eventually died of prostate cancer compared with 31 of the 348 men (group 2) who did not have surgery. The researchers want to determine if surgery increases the chance of survival. Let p1: proportion of men that survived after...
