(B) Select the correct choice below and, if necessary, fill in any answer boxes to complete choice. A. The 90% confidence interval is (____,____) (Round to two decimal places as needed.) B. Neither distribution can be used to construct the confidence interval. (C) Interpret the results. Choose the correct answer below A. It can be said that 99% of plavers have a vards per carry between the bounds of the confidence interval. B. With 99% confidence. it can be said that the population mean vards per carry is between the bounds of the confidence interval. C. If a large sample of plavers are taken approximately 99% of them will have vards per carry between the bounds of the confidence interval. D. Neither distribution can be used to construct the confidence interval

Use the standard normal distribution or the t-distribution to construct a 99% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a recent season, the population standard deviation of the yards per carry for all running backs was 1.38. The yards per carry of 25 randomly selected running backs are shown below. Assume the yards per carry are normally distributed. 2.3 2.8 7.2 3.3 5.5 6.4 1.2 5.1 4.2 5.2 6.6 2.2 1.7 7.1 3.9 5.2 47 6.8 4.1 5.4 4.3 4.5 3.7 4.6 2.7 Which distribution should be used to construct the confidence interval? O A. Use a normal distribution because n
