Throughout the country, the proportion of first time, first-year community college students who return for their second year of studies is 0.52 according to the Community College Survey of Student Engagement. Suppose a community college institutes new policies geared toward increasing student retention. The first year of this policy there were 2843 first-time, first-year students of which 1516 returned for their second year of studies. Treat these students as a random sample of all first-time, first-year students. Do a statistically significant higher proportion of students return for their second year under this policy? Use the a = 0.1 level of significance. Would you say the results are practically significant? In other words, do you believe the results are significant enough that other community colleges might consider

emulating these same policies?
