Chapter Test Confidence intervals 6. The gas mileages (in miles per gallon) of 27 randomly selected sports cars are listed in the accompanying table. Assume the mileages are not normally distributed. Use the standard normal distribution or the t-distribution to construct a 95% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why, Interpret Click the icon to view the sports car gas mileages. Let a be the population standard deviation and let n be the sample size. Which distribution should be uted to construct the confidence interval? the results. (1) be used to construct the confidence interval, since (2) Identify the confidence interval. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA (Round to one decimal place as needed.) O B. Neither the standard normal distribution nor the t-distribution can be used to construct the interval. Interpret the results.
