Use the results from a survey of a simple random sample of 1281 adults. Among the 1281 respondents, 81% rated themselves as above average of adults rate drivers. We want to test the claim that more than 3 4 themselves as above average drivers. Complete parts (a) through (e). a. Regardless of the conclusion reached from the hypothesis test, is it possible that more than 3 4 of adults can be above average drivers? A. Yes. Assuming quality of driving can be quantified, a distribution that is extremely skewed to the left would be the most promising scenario for more than this proportion of adults to have driving quality that is above the mean. OB. Yes. Assuming quality of driving can be quantified, a distribution that is extremely skewed to the right would be the most promising scenario for more than this proportion of adults to have driving quality that is above the mean. OC. No. Assuming quality of driving can be quantified, half of all adults must have driving quality less than or equal to the mean. OD. No. It is impossible to compare the quality of different adults' driving. Use the results from a survey of a simple random sample of 1281 adults.
