Use the standard normal distribution or thet-distribution to construct a 99% confidence interval for thepopulation mean. Justify your decision. If neither distribution canbe used, explain why. Interpret the results. In a randomsample of 42people, the mean body mass index (BMI) was 27.5 and the standard deviation was 6.05. Whichdistribution should be used to construct the confidence interval?Choose the correct answer below. A. Use a t-distributionbecause the sample is random, n30, and is unknown. B. Use anormal distribution because the sample is random, the populationis normal, and is known. C. Use a t-distribution becausethe sample is random, the population is normal, and isunknown. D. Use a normal distribution because the sample israndom, n30, and is known. E. Neither a normal distributionnor a t-distribution can be used because either the sample is notrandom, or n30, and the population is not known to be normal.Select the correct choice below and, if necessary,
