A study regarding the proportion of students who finish their MS degree (graduate) is conducted in two universities (A and B). The results are shown in the following table.

a. Construct a lower bound (LB) 99% confidence interval for difference of true graduation proportions (p – Py). b. Do the data show enough evidence to suggest that University A has the same graduation proportion as University B at a = 0.05? Zo.025 = 1.96 Zo.05 = 1.65 Z0.01 = 2.33 Z0.005 = 2.58 University A Pr = 0.75 University B Py = 0.72 m = 81 n = 64
