Question: Use the t -distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from random samples, and

Use the t -distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal.

Test H0:1=2 vs Ha:1>2 using the sample results x1=56 , s1=8.2 with n1=30 and x2=51 , s2=6.9 with n2=40 .
