In a hypothesis test for the population variance, the alternate hypothesis is the population variance doesn't equal 17.0. The significance level to be used is 0.05 and the sample size to be taken is 25. The table value(s) to use from the chi-square distribution is/are A. 13.181 B. 12.401 and 39.364. C. 40.671 D. 39.364

Step 1
In this case, the hypothesis test is for the population variance, and the alternate hypothesis is that the population variance does not equal 17.0. This is a two-tailed test because the alternate hypothesis includes variances both greater than and less than 17.0. Show more…

A hypothesis will be used to test that a population mean equals 7 against the alternative that the population mean does not equal 7, with known variance ̃. What are the critical values for the test statistic z for the 0.01 significance level? Select one: a. -2.58 and 2.58 b. -4.12 and 4.12 c. -0.01 and 0.01 d. -0.05 and 0.05 e. -3.25 and 3.25

In a test of hypotheses the null hypothesis is that the population mean is equal to 125 and the alternative hypothesis is that the population is greater than 125. A sample of 100 elements selected for this population produced a mean of 129.9 with the population standard deviation of 17. what is the approximate p-value for this test? a) 0.0200 b) 0.0080 c) 0.0040 d) 0.0020

A hypothesis will be used to test that a population mean equals 10 against the alternative that the population mean is more than 10 with known variance $\sigma$. What is the critical value for the test statistic $Z_{0}$ for the following significance levels? (a) 0.01 (b) 0.05 (c) 0.10
