Extracted text: (d) If the test procedure with a = 0.006 is used, what n is necessary to ensure that B(70) = 0.01? (Round your answer up to the next whole number.) n = specimens (e) If a level 0.01 test is used with n = 100, what is the probability of a type I error when u = 76? (Round your answer to four decimal places.)
