Statistics

Find the critical values for the indicated test for a population variance, sample size n, and the level of significance "a".

1. Left-tailed test, n = 27, = 0.05

2. Two-tailed test, n = 15, = 0.05

3. Right-tailed test, n = 41, = 0.10

Problems 9-12. State whether the standardized test statistic X(2) allows you to reject the null hypothesis for a two-tailed test with X(2)L = 6.408 and X(2)R = 33.409.

4. X(2) = 35.00

5. X(2) = 28.75

6. X(2) = 8.40

7. X(2) = 6.25
