(a) Use statistical software such as Minitab or StatCrunch to obtain 1500 simple random samples of size n = 5 from a normal population with μ = 50 and σ = 10. Calculate the sample mean and sample standard deviation for each sample. Compute

for each sample. Draw histograms for both z and t.

(b) Repeat part (a) for 1500 simple random samples of size n = 10.
