1. The 2014 General Social Survey asked respondents who worked full or part time the week prior to survey, "During the past 30 days, for about how many days did your poor physical or mental health keep you from doing your usual activities, such as self-care, work, or recreation?"(0 to 30). The mean response for the 95 foreign-born men in the sample was 0.45 days with a standard deviation of 1.39 days. Among the 512 U.S.-born men in the sample, the mean response was 1.21 days with a standard deviation of 4.18 days. Is there evidence that in the population of U.S. adults foreign-born men tend to have on average fewer days of activity limitation in the past 30 days than U.S.-born men? Answer the question by using the information provided and conducting a two-samples t test. Give the null and research hypotheses, find the p-value, identify the decision rule, indicate your decision and on what it is based, and interpret the result. Use a rejection level or alpha of .05. Show all steps. Label the parts of your answer using the outline below. (Hint: You do not have to calculate the obtained t or its associated degrees of freedom. They were generated using the SPSS statistical software package, and are given in the outline below.)
