A simple random sample of 37 UC Davis students yields an average GPA of 2.71. Assume that the standard deviation of all UC Davis students’ GPA’s is 0,56. Perform a hypothesis test to determine whether this result provides strong evidence that the overall average GPA of all UC Davis students is above 2.5 . a. Clearly state the test hypotheses as follows: Let …… represent the overall ….. H0 : ….. ,H1 : …… b. It’s known that the test statistic is 2.28. Use an appropriate table to find or estimate the p-value c. Use the p-value to draw the explain your conclusion of the test
