Asimple random sample has a sample size of n=65. given the population is normally distributed, find the critical value t a/2 corresponding to a 99% confidence level

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The answer is the first one
