Retention of students after freshman year is always important at SMC. The college noticed after 2018 that the rat of retention was 78%. So in 2019 they have decided to implement new policies toward increasing student retention. After the first year of the policy there were 342 first time first year students of which 278 returned for the second year of studies. Treat these students as a random sample of all first time first year students. Did a statistically significant higher proportion of students return for their second year under this policy? Use alpha level = .1 In other words do you believe the results are significant enough that these changes be made permanent?

Expert Solution

Test for single proportion:

H0: There is statistically significant not higher proportion of students return for their second year under this policy

H1: There is statistically significant higher proportion of students return for their second year under this policy

Thus we conculde that there is statistically significant higher proportion of students return for their second year under this policy
