Past studies have indicated that 85.6% of all enrolled college students in the U.S are undergraduates. A random sample of 500 enrolled college students in a particular stat revealed that 420 of the students were undergraduates. Is there enough evidence to conclude that the percentage of undergraduates from this particular state differs from the national percentage? A. What type of test would be appropriate for this situation? (Name the test and indicate if it should be a one tailed test or a two tailed test) B. State the Null and the alternate hypothesis. C. Perform the appropriate test and report the P- Value. D. Use your P-Value to make a conclusion about the problem. Are you accepting or rejecting the null hypothesis?
