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=4 vs Ha : μ≠4 using the sample results x¯=4.8, s=2.3,
with n=15.
