Students in the senior capstone course (N=36) at Central State University took the Political Science subtest developed by the National Board Testing Association. The test is a 75-item, multiple choice test covering all areas of political science. The national norms for the test show a mean of 50. The mean for the students in the capstone course was 55, with a standard deviation of 15. Did the students at CSU score significantly higher than the national average? State your null and alternative hypothesis Is this a one-or-two tailed hypothesis? Explain thoroughly. Calculate the appropriate statistical test. Can you reject the null hypothesis? Why or why not?
2. University researchers claim that the average enrollment at four-year colleges is higher than two-year community colleges. Two surveys are undertaken at 35 four-year universities and 35 two-year colleges. The mean enrollment at the four-year institutions was 5,466 with a standard deviation of 8,191. The average enrollment at the two-year schools was 5,068 with a standard deviation of 4,777. Using a 95% confidence level, are the findings of the surveys consistent with the university researchers’ claim? 2. Does the null hypothesis reject H0 or fail to reject H0?
