SCENARIO 12-4 A computer used by a 24-hour banking service is supposed to randomly assign each transaction to one of 5 memory locations.A check at the end of a day's transactions gave the counts shown in the table to each of the 5 memory locations,along with the number of reported errors. The bank manager wanted to test whether the proportion of errors in transactions assigned to each of the 5 memory locations differ. -Referring to Scenario 12-4,which test would be used to properly analyze the data in this experiment? A)$\chi$ ²test of independence B)$\chi$²test for difference among more than two proportions C)Wilcoxon rank sum test D)Kruskal-Wallis rank Test

Question

Quizplus · Accepted Answer

The scenario involves comparing the proportion of errors in transactions assigned to each of the 5 memory locations. Therefore, we need to use a test for difference among more than two proportions. Option A is incorrect because it is used for testing independence between two categorical variables. Options C and D are used when the data is not normally distributed or the assumptions of parametric tests are not met.
