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.) (c) What area of the z-distribution should be shaded for the p-value in Step 3 of the hypothesis test?

By 2050, Hispanics will make up 24.5 percent of the population, up from 10.2 percent in 1996. The annual growth rate of the Hispanic population is expected to be 2 percent through the year 2030. To put this growth in perspective, consider the fact that even at the height of the baby boom explosion in the late 1940s and 1950s, the country’s annual population increase never reached 2 percent. Demographers, it seems, are alerting us to the enormous importance of such a change. Says Gregory Spencer, Director of the Census Bureau’s Population Projections Branch, “The world is not going to be the same in thirty years as it is now.”
