Suppose that a company claims that 67% of their employees (about 2/3) buy annual parking permits for parking at their workplace. A random survey of 120 employees finds that 62 of them have annual parking permits.
Given that the pair of hypotheses that correspond to the claim are as follows:
H0: p = 0.67
H1: p # 0.67
Find the critical values for the hypothesis test. Assume that the significance level is a=0.01
Answer: z = ± ________________
