A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 236 vinyl gloves, 67% leaked viruses. Among 236 latex gloves, 8% leaked viruses.Using the accompanying display of the technology results, and using a 0.05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves.

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $20,000 and $45,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired.
Lightning Deaths The graph in Cumulative Review Exercise 5 was created by using data consisting of 232 male deaths from lightning strikes and 55 female deaths from lightning strikes. Assume that these data are randomly selected lightning deaths and proceed to construct a 95% confidence interval estimate of the proportion of males among all lightning deaths. Based on the result, does it seem feasible that males and females have equal chances of being killed by lightning?

Self-Reported and Measured Male Heights As part of the National Health and Nutrition Examination Survey, the Department of Health and Human Services obtained self-reported heights (in.) and measured heights (in.) for males aged 12–16. Listed below are sample results. Construct a 99% confidence interval estimate of the mean difference between reported heights and measured heights. Interpret the resulting confidence interval, and comment on the implications of whether the confidence interval limits contain 0.
