To test the hypothesis that two population variances are equal, a random sample of size 13 was selected from the first population, and a random sample of size 21 was selected from the second population. What are the degrees of freedom to test the hypothesis?
Added by Carlos M.
Step 1
Step 1: Calculate the degrees of freedom for the numerator: Given that the sample size from the first population is 13, the degrees of freedom for the numerator is calculated as \(n_1 - 1 = 13 - 1 = 12\). Show more…

To test the hypothesis that two population variances are equal, a random sample of size 13 was selected from the first population, and a random sample of size 21 was selected from the second population. Given that the sample standard deviation from the first population is larger than the sample standard deviation from the second population, what is the F critical value using 0.01 as the significance level?

For a hypothesis test comparing two independent population means, the combined degrees of freedom are 48. Which of the following statements about the two sample sizes cannot be true? Assume the population standard deviations are unknown but equal. Multiple Choice n1 = 25; n2 = 25 n1 = 24; n2 = 26 n1 = 23; n2 = 25 n1 = 22; n2 = 28 We test for a hypothesized difference between two independent population means: H0: μ1 = μ2. The population standard deviations are unknown but assumed equal. The number of observations in the first sample is 30 and 27 in the second sample. How many degrees of freedom are associated with the critical value? Multiple Choice 54 55 56 57

Critical Thinking The $x$ distribution must be normal in order to use a chi-square distribution to test the variance. What are some methods you can use to assess whether the $x$ distribution is normal? Hint: See Chapter 6 and goodness-of-fit tests.
