What is the t-critical value? (a) 2.131847 (b) 2.776445 (c) 1.859548038 (d) 2.306004

What is the p-value? (a) 0.05712 (b) 0.11424 (c) 0.015598 (d) 0.031197

At a = 0.05, what is the correct decision? (a) Do not reject the null hypothesis (b) Reject the alternative hypothesis (c) Reject the null hypothesis (d) Do not reject the alternative hypothesis

The following are measurements of the heat-producing capacity (in millions of calories per ton) of
random samples of five specimens each of coal from two mines:
Mine 1:
8380 8210 8360 7840 7910
AVI
Mine 2:
7540 7720 7750 8100 7690
Below are the EXCEL outputs of the data at 95% confidence level:
