A university is interested in promoting graduates of its honors program by establishing that the mean GPA of these graduates exceeds 3.50. A sample of 36 honors students is taken and is found to have a mean GPA equal to 3.4. The population standard deviation is assumed to equal 0.40. a. Construct the hypotheses H0 and HA b. What is the p-value if a =0.05? c. At the 5% significance level, does the university reject the null hypothesis?

A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20. In a sample of 200 graduates, 30 students have a GPA of 3.00 or below. In testing the university's belief, the appropriate hypotheses are Multiple Choice H. :p -0.15, HP 0.15 O H.:P <0.20, HAP >0.20 O Ha :P> 0.15, HP< 0.16 O HP 20.20, HAP<0.20
