When performing a chi squaredχ2 test for independence in a contingency table with r rows and c columns, determine the upper-tail critical value of the test statistic in each of the following circumstances. b. alpha = 0.01, r = 5, c = 3 c. alpha = 0.01, r = 5, c = 4 d. alpha = 0.01, r = 3, c = 4 e. alpha = 0.01, r = 4, c = 5 QUESTION: what are the critical values for...
When we carry out a chi-square test of independence, the chi-square statistic is based on (rxc)-1 degrees of freedom, where r and c denote, respectively, the number of rows and columns in the contingency table. True or false
1. Use the data in the contingency table to answer the question. Columns Rows 1 2 3 Total 1 36 35 92 163 2 67 57 113 237 Total 103 92 205 400 You wish to test the null hypothesis of "independence"—that the probability that a response falls in any one row is independent of the column it falls in—and you plan to use a chi-square test. You are given that there are 2 degrees of freedom associated with the...
Find the rejection region for a test of independence of two classifications where the contingency table contains r rows and c columns. A. r = 3, c = 6, alpha = 0.10
You intend to conduct a test of independence for a contingency table with 8 categories in the column variable and 2 categories in the row variable. You collect data from 349 subjects. What are the degrees of freedom for the ? 2 distribution for this test? d.f. =

The table below gives a two-way classification for these students.GenderOn TimeLateFemale359Male4313For a chi-square test of independence for this contingency table, what is the number of degrees of freedom?
10.00 points When we carry out a chi-square test of independence, the alternate hypothesis states that the two relevant classifications O are mutually exclusive. O form a contingency table with rrows and c columns O have (1 - 1)(C-1) degrees of freedom are statistically dependent O O are normally distributed
