2. Mr. Sy asserts that fewer than 5% of the bulbs that he sells are defective. Suppose 300 bulbs are randomly selected, each are tested and 10 defective bulbs are found. Does this provide sufficient evidence for Mr. Sy to conclude that the fraction of defective bulbs is less than 0.05? Use a = 0.01. A. We rejected the null hypothesis since the computed probability value is lesser than - 1.28. B. Accept alternative hypothesis since the computed probability value is greater than 0.05. C. We reject the null hypothesis since there is no sufficient evidence to reject Mr. Sy's statement. D. We cannot reject the null hypothesis since there is no sufficient evidence to reject Mr. Sy's statement.
