a.) 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
5% beyond them in each tail if the sample has size n=8.
Round your answer to three decimal
places.
endpoints = +-
b.) 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
0.025 beyond them in each tail if the sample has size n=25
Round your answer to three decimal
places.
