As a follow-up to a report on gas consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage for their vehicles. A simple random sample of 83 SUV owners was selected, and the owners were asked to report their highway mileage. The results that were summarized from the sample data were x = 19.2 mpg and s = 5.4 mpg. Based on these sample data, compute and interpret a 95% confidence interval estimate for the mean highway mileage for SUVs. The 95% confidence interval is mpg- mpg. (Round to one decimal place as needed. Use ascending order.) Interpret this interval. Choose the correct answer below. A. There is a 0.95 probability that the true mean highway mpg for SUVS falls in this range. OB. One can conclude with 95% confidence that the true mean highway mpg for SUVS is in this range. O C. One can conclude with 95% confidence that the sample mean highway mpg for SUVS is in this range. OD. One can conclude that the true mean highway mpg for SUVs will fall in this range 95% of the time. 1x= Consider the following hypothesis test with n = 21, s = 6.9, and x = 64.9. Hoi H=62 #62 x = 0.01 a. State the decision rule in terms of the critical value of the test statistic. b. State the calculated value of the test statistic. c. State the conclusion. a. State the decision rule. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) A. Reject the null hypothesis if the calculated value of the test statistic is greater than the critical value of B. Reject the null hypothesis if the calculated value of the test statistic is less than the critical value of C. Reject the null hypothesis if the calculated value of the test statistic is less than the critical value of b. State the calculated value of the test statistic. (Round to two decimal places as needed.) c. State the conclusion. Choose the correct answer below. A. Do not reject the null hypothesis. There is not sufficient evidence that the mean is not equal to 62. O B. Reject the null hypothesis. There is sufficient evidence that the mean is not equal to 62. C. Do not reject the null hypothesis. There is sufficient evidence that the mean is not equal to 62. OD. Reject the null hypothesis. There is not sufficient evidence that the mean is not equal to 62. Otherwise, do not reject. Otherwise, do not reject. or greater than the critical value of Otherwise, do not reject.
