(b) If the researcher decides to test this hypothesis at the = 0.01 level of significance, determine the critical values. The critical values are 2.831, 2.831 (Use a comma to separate answers as needed.

Explanation / Answer
The degrees of freedom is: n-1=18-1=17
The critical values are t(0.01,17)=+/-2.8983
