Hi!

Can you please help me use problem 2 to solve for problem 3! You are solving for problem 3 only!

Problem 2) A sample of 30 latest earnings-per-share (EPS) for XYZ stock reveals a mean EPS of $4 with a sample standard deviation of $0.13. Estimate and interpret the SE of the sample mean to two decimal places.

Problem 3) Suppose we increased the sample size to 80 in problem #2 (above) and derived similar values for the mean and standard deviation of EPS. Estimate and interpret the SE of the sample mean and why it changed from problem 3.

Thanks!
