Use the t-distribution and the sample results to
complete the test of the hypotheses. Use a 5% significance level.
Assume the results come from a random sample, and if the sample
size is small, assume the underlying distribution is relatively
normal.
Test H0 : μ=100 vs Ha : μ<100 using the sample results x¯=91.7,
s=12.5, with n=30.
