Suppose the following hypotheses are to be tested. Ho: PA=PB and H₁: MAHB for two populations in which the population variances are known and have the values o = 12 and 0²/B = = 15 respectively. Two samples of sizes 29 and 9 respectively were collected. The data were not paired. According to the flowcharts presented in M140, which hypothesis test should be used? (You may assume that any additional requirements for your selected test, such as normality and/or equal population variances are satisfied.) Select one: Matched-pairs t-test Sign test Two-sample t-test X² test for contingency tables One-sample z-test One-sample t-test OTwo-sample z-test 000
