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
df = (r - 1) * (c - 1) = 2 * 5 = 10

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...
Chapter 11, Section 11.3, Problem 021 Consider the following contingency table that is based on a sample survey. Column 1 Column 2 Column 3 Row 1 133 83 84 Row 2 90 52 | 91 | Row 3 1367996 a. Write the null and alternative hypotheses for a test of independence for this table. Ho: Rows and columns are H: Row and columns are b. Calculate the expected frequencies for all cells assuming that the null hypothesis is true. b....
When testing for independence in a contingency table with 4 rows and 4 columns, there are____ degrees of freedom
When performing a x2 test for independence in a contingency table with r ro circumstances a. a 0.05, r 5, c-3 c. a 0.01, r 4, c 6 a. Determine the upper-tail critical value of the test statistic using the values d.a0.01, r 3, c 6 e.a 0.01, r 6,c 5 The critical value is (Type an integer or a decimal. Round to three decimal places as needed
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...
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
CH12 Q4 Given the following contingency table, conduct a test for independence at the 1% significance level. (You may find it useful to reference the appropriate table: chi-square table or F table) Variable A Variable B 31 34 32 58 a. Choose the null and alternative hypotheses. OH: The two variables are independent.; H: The two variables are dependent. 0 0: The two variables are dependent. ; HA: The two variables are independent. b. Calculate the value of the test...
