Hello, can you please explain to me of this math problem. Break this math problem down for me to understand . Thank you. Use the standard normal distribution or the t- distribution to construct a 99% confidence interval for the population mean. Justifty your decision if neither distribution can be used explain. Why Intepret 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. 1.6, 4.8, 7.2, 4.5, 7.3, 7.3, 5.7, 2.6, 7.4, 1.9, 1.5, 4.3, 7.4, 3.9, 5.6, 3.3, 4.4, 3.5, 2.9, 4.3, 6.6, 2.7, 7.3, 6.9, 7.5 Which distribution should be used to construct the confidence interval? Use a normal distribution because σ is known and the data are normally distributed. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (A). The 99% confidence interval is______, ________ (Round to two decimal places as needed.) (B). 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
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
1.6, 4.8, 7.2, 4.5, 7.3, 7.3, 5.7, 2.6, 7.4, 1.9, 1.5, 4.3, 7.4, 3.9, 5.6, 3.3, 4.4, 3.5, 2.9, 4.3, 6.6, 2.7, 7.3, 6.9, 7.5
Which distribution should be used to construct the confidence interval?
Use a normal distribution because σ is known and the data are normally distributed.
Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice.
(A). The 99% confidence interval is______, ________
(Round to two decimal places as needed.)
(B). Neither distribution can be used to construct the confidence interval.
