A researcher randomly sampled 30 graduates of an Master program and recorded data concerning their starting salaries. Of primary interest to the researcher was the effect of gender on starting salaries. Analysis of the mean salaries of the females and males in the sample is given below. Std Dev 48,266.7 13,577.63 11,741.29 Size Mean Females Males 18 12 55,000 Std Error = 4,764.82 Means Diff=- 6,733.3 Z=- 1.4528 2-tailed p-value = 0.1463 =-1.4221 2-tailed p-value = 0.1574 Referring to the table, the researcher was attempting to show statistically that the female Master graduates have a significantly lower mean starting salary than the male Master graduates. According to the test run, which of the following is an appropriate alternative hypothesis?
