SCENARIO 10-2
A researcher randomly sampled 30 graduates of an MBA program and recorded data concerning their starting salaries.Of primary interest to the researcher was the effect of gender on starting salaries.
The result of the pooled-variance t-test of the mean salaries of the females (Population 1)and males (Population 2)in the sample is given below.

-Referring to Scenario 10-2,the researcher was attempting to show statistically that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.From the analysis in Scenario 10-2,the correct test statistic is:
A)-6610
B)-1.3763
C)-1.7011
D)0.0898

Quizplus · Accepted Answer

The correct test statistic for comparing means between two independent samples (in this case, male and female MBA graduates) is typically a t-statistic. Among the options given, -1.3763 is the only value that resembles a t-statistic, as it falls within a range that could be plausible for such a test. The other values either are too extreme or do not fit the context of a t-test statistic.
