H0 : p = 0.63 Ha : p < 0.63 where p is the true proportion of drive-thru customers who have to wait more than two minutes. Suppose that the manager decided to carry out this test using a random sample of 250 orders and a significance level of α = 0.22. What is the probability of making a Type I error? Round your answer to two decimal places.
