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 random sample of 47 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.17. OE. Neither a normal distribution nor a t-distribution can be used because either the sample is not random, or n<30, and the population is not known to be normal. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. OA. The 99% confidence interval is ( (Round to two decimal places as needed.) B. Neither distribution can be used to construct the confidence interval.
