Suppose we want to test the hypothesis that the probability that a semiconductor is defective is less than 0.05. To this end, we take a sample of 200 devices and find that 6 are defective. At level of significance 0.05, what can we conclude? O a. The z statistic -1.3, and the p-value 0.046. Therefore, we reject the null hypothesis. O b. The z statistic -2.3, and the p-value 0.03. Therefore, we reject the null hypothesis. O. The z statistic -1.3, and the p-value 0.096. Therefore, we fail to reject the null hypothesis. O d. Background conditions are not satisfied, therefore we cannot conduct this hypothesis test.
