Question 72

Multiple Choice

Assume the competing hypotheses take the following form H0: µ1-µ2 = 0,HA: µ1-µ2 ≠ 0,where µ1 is the population mean for population 1 and µ2 is the population mean for population 2.Also assume that the populations are normally distributed with known variances and we use independent sampling.Which of the following expressions is appropriate test statistic?
