Hint: Find the critical value for each test; then make a decision. (Round your critical values to two decimal places.) Part (a) F(3, 26) = 3.03 Ferit- Retain the null hypothesis. Reject the null hypothesis. EPart (b) F(5, 18)=2.61 Fcnt O Retain the null hypothesis. O Roject the null hypothesis. Part (c) F(2, 13) 3.71 Fant Retain the null hypothesis. Reject the null hypothesis. Part (d) F(4, 34)- 2.69 Fcnt O Retain the null hypothesis O Reject the null hypothesis.
