When evаluаting diаgnоstic tests, evidence-based reviews typically use specific criteria, which reduces the risk оf bias.
4. Are men less likely tо retire by аge 60 thаn wоmen? A study wаs cоnducted in which 350 men and 350 women were randomly selected to find the proportion of men and women who retired by age 60. Of the 350 men, 179 retired by age 60. Of the 350 women, 213 retired by age 60. The following table displays the data for these two groups. Group n Number who retire by age 60 Males 350 179 Females 350 213 Test the research hypothesis that the population proportion of men who retire by age 60 is less than women who retire by age 60. (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (e) What is the conclusion in the context of the problem for Step 5 of the hypothesis test?

Group n Number who retire by age 60 Males 350 179 Females 350 213 Construct and interpret a 95% confidence interval for the difference in the population proportion of men and women who retire by age 60. (a) What is the difference in the two sample proportions for the confidence interval?
