Question

8. In a test for the population variance (?²), the hypotheses to be tested are: H0: ?² = 25 versus H1: ?² < 25 If the sample size is 20 and the test is being carried out at the 10% level of significance, the null hypothesis will be rejected if: x-square > 10.117 x-square > 10.851 x-square < 12.443 x-square < 11.651

          8. In a test for the population variance (?²), the hypotheses to be tested are: 
H0: ?² = 25 versus H1: ?² < 25 
If the sample size is 20 and the test is being carried out at the 10% level of significance, the null hypothesis will be rejected if:
x-square > 10.117
x-square > 10.851
x-square < 12.443
x-square < 11.651

In a test for the population variance (σ²), the hypotheses to be tested are: H0: σ² = 25 versus H1: σ² < 25. If the sample size is 20 and the test is being carried out at the 10% level of significance, the null hypothesis will be rejected if: χ-square > 10.117 χ-square > 10.851 χ-square < 12.443 χ-square < 11.651
