Indicate whether the statement is true or false Q. 2 The Wilcoxon rank sum test is a nonparametric test that measures the degree of association between two variables for which only rank-order data are available. Indicate whether the statement is true or false Q. 3 To be valid, the chi-square test requires that all expected frequencies equal: a. 30 or more b. 30 or less c. 30 precisely d. both 30 or more and 30 or less e. none of these Q. 4 The chi-square technique has numerous applications, including: a. testing the alleged independence of two qualitative variables b. making inferences about the relative sizes of more than two population proportions c. conducting a goodness-of-fit-test to determine whether data are consistent with data drawn from a particular probability distribution d. all of these e. none of these Q. 5 The total degrees of freedom for an r x c (fixed-column) contingency table are rc + 1. Indicate whether the statement is true or false Q. 6 If there are more than two row categories in a contingency table with fixed c column totals, then the test of independence is equivalent to a test of the equality of c sets of multinomial proportions.
