A television manufacturer claims that (at least) 90% of its TV sets will not need service during the first 3 years of operation. A consumer agency wishes to check this claim, so it obtains a random sample of n = 100 purchasers and asks each whether the set purchased needed repair during the first 3 years after purchase. Let p be the sample proportion of responses indicating no repair (so that no repair is identified with a success). Let p denote the actual proportion of successes for all sets made by this manufacturer The agency does not want to claim falsa advertising unless sample evidence strongly suggests that p < 0.9. The appropriate hypotheses are then Hopa obversus HP<0.9 (a) in the context of this problem, describe Type I and Type II errors. (Select all that apply) D A Type 1 error would be not obtaining convincing evidence that less than 90% of the TV sets need no repair when in fact less than 90% need no repair A Type 1 error would be obtaining convincing evidence that less than 90% of the TV sets need no repair when in fact (at least) 903 need no repair A Type It error would be obtaining convincing evidence that less than 90% of the TV sets need no repair when in fact (at least) 90% need no repair A Type 11 error would be not obtaining convincing evidence that less than 90% of the TV sets need no repair when in fact less than 90% need no repale.
