question: 1 point(s) possible Use the results from a survey of a simple random sample of 1259 adults. Among the 1259 respondents, 73% rated themselves as above average drivers. We want to test the claim that more than of adults rate themselves as above average drivers. Complete parts (a) through (e). 13 20 b. If we use the same significance level to conduct the hypothesis test using the P-value method, the critical value method, and a confidence interval, which method is not always equivalent to the other two? OA. The confidence interval method is not always equivalent to the other two. OB. The P-value method is not always equivalent to the other two. OC. The critical value method is not always equivalent to the other two. OD. All three methods are always equivalent to each other. c. It was stated that we can easily remember how to interpret P-values with this: "If the P is low, the null must go." What does this mean? This statement means that if the is low in relation to then one should the d. Another memory trick sometimes used is this: "If the P is high, the null will fly." Given that a hypothesis test never results in a conclusion of proving or supporting a null hypothesis, how is this memory trick misleading? OA. This statement seems to suggest that with a high P-value, the alternative hypothesis has been rejected, but this conclusion cannot be made. B. This statement seems to suggest that with a high P-value, the null hypothesis has been proven or is supported, but this conclusion cannot be made. C. This statement seems to suggest that with a low P-value, the null hypothesis has been proven or is supported, but this conclusion cannot be made. OD. This statement seems to suggest that with a high P-value, the alternative hypothesis has been proven or is supported, but this conclusion cannot be made. e. Common significance levels are 0.01 and 0.05. Why would it be unwise to use a significance level with a number like 0.0457? OA. Choosing such a specific significance level could give the impression that the significance level was carefully chosen to reach a desired conclusion. B. Using a significance level to more decimal places makes calculations of P-values more difficult. Hoult to coinct the null hypothesis.
