A batch of 30 semiconductor chips is inspected by choosing a sample of 4 chips. Assume 10 of the chips do not conform to customer requirements. What is the probability that the sample of 4 contain exactly one nonconforming chip? none of these answers 0.17679 0.00036 0.87575 0.41598Given the hypotheses Ho : H=50 vs H1/ *50 : . Assume that o is known. If the value of the test statistic is 1.36, then the p-value= O 0.4131 > 0.0869 O 0.1033 0.2066 O 0.1738
