Does the boxplot suggest that it is reasonable to construct a confidence interval for the population mean? A. Yes, the distribution is roughly symmetric and there are no outliers. O B. No, the distribution is roughly symmetric with no outliers. O C. No, the boxplot shows there are outliers. O D. Yes, the distribution is highly skewed with outliers. If the boxplot suggests a confidence interval can be constructed, calculate and interpret the lower bound and the upper bound of the confidence interval. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Round to the nearest dollar. Use ascending order.) A. We are 95% confident that the mean cost of repair is between $ 1022 and $ 2473. O B. There is a 95% probability that the mean cost of repair is between $ and $ O C. The confidence interval should not be constructed. (c) Suppose you obtain a simple random sample of size n = 10 of a Mini Cooper that was in a low-impact collision and determine the cost of repair. Do you think a 95% confidence interval would be wider or narrower? Explain. O A. Narrower, because there is less variability in the data because any variability caused by the different types of vehicles has been removed. O B. Wider, because there is more variability in the data because variability in the repair cost of the car has been added. C. Narrower, because taking a second random sample will always lead to a narrower confidence interval. O D. Wider, because taking a second random sample will always lead to a wider confidence interval.

The approval rating is reported as the proportion of the population who approve of the job that the sitting president is doing and is typically based on a random sample of registered voters where the sample size is the same week to week. Complete parts (a) and (b) below. a) This proportion tends to fluctuate from week to week. Name some reasons for the fluctuation in the statistic. Select all valid reasons below. A. The proportion could be changing due to a large change in the composition of the population. Ly B. The proportion could be changing because people's attitudes are changing. Y C. The proportion could be changing due to sampling error; different people are in the sample. D. The proportion could be changing because the sampling size of the poll is changing b) A poll showed the approval rating to be 0.43 (43%). A second poll based on 2000 randomly selected voters showed that 878 approved of the job the president was doing. Do the results of the second poll indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original level? Explain.

Use the a = 0.01 level of signicance. Because npo (1 - p0) = 47.1 > 10, the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satised.
