Exercise 10-11 CAS Exam 3 Spring 2005 #22
Drivers are classified as "good" or "bad." Results of the classification are assumed to be

100 drivers. Determine the critical value for testing the hypothesis p<0.5 with
significance level alpha of at most 0.05 using the normal approximation.
(A) Less than 52
(B) At least 52, but less than 54
(C) At least 54, but less than 56
(D) At least 56 , but less than 58
(E) 58 or more answer should be E
