TI-84: Look at a table of critical values of F. Excel: Look at Fcrit . Step 5: Decide to reject or not reject the null hypothesis. Calculated F < critical F → null hypothesis . not rejected. Calculated F > critical F → null hypothesis . is rejected. Critical F at 0.05 level.= 3.35; calculated F of 20.70 > 3.35. The null hypothesis . is rejected

For the positive critical value (2.5% to the right), they are looking for the value where 97.5% of the area is to the left. Students will use the . invT. command to find a critical value for a t distribution and use the . invNorm . command to find the critical value for the normal distribution. Remind them that d.f. is n –1.
