Find the values of t that bound the middle 0.8 of the distribution for df = 30. (Give your answers correct to two decimal places.) ------to-----
10 DF Question 5 For the same t distribution in the last question, what is the p-value for a test statistic of -2.228? a. 0.01 b. 0.025 c. 0.05 d. 0.10
A chi-square test for goodness of fit is used to examine the distribution of individuals across three categories, and a chi-square test for independence is used to examine the distribution of individuals in a 2×3 matrix of categories. Which test has the larger value for df? a. The test for independence b. Both tests have the same df . c. The df value depends on the sizes of the samples that are used. d. The test for goodness of fit
Using the t distribution table in your text, (Figure 10.11) and identify the df and critical value at α = .05, for a one-tailed test with n = 11. Thank you!!
• Show that the tension T of the string is related to the fundamental frequency f1 by where L is the length of the string, and u is the linear mass of the string.
1. Suppose t hat Xhas t he chi-square distribution on p1∈(0, ∞) degrees of f reedom and that, i ndependently, Y has t he chi-square distribution on p2∈(0, p1) degrees of f ree-dom. a. Use moment generating functions to find the distribution of X + Y . b. A naive guess might be that the distribution of X − Y is chi-square on p1− p2 degrees of freedom. Prove that such a guess is wrong by demonstrating that P (X...
