Assume the sample is a random sample from a distribution that is reasonably normally distributed and we are doing inference for a sample mean. Find endpoints of a t-distribution with 0.005 beyond them in each tail if the sample has size $n = 31$. Round your answer to three decimal places. endpoints = \pm

Step 1
The degrees of freedom for a t-distribution is calculated as n-1, where n is the sample size. In this case, n=31, so the degrees of freedom (df) is 31-1 = 30. Show more…
