Is there any systemic tendency for full-time college faculty to hold their students to different standards than part-time faculty do? A sample of 125 courses taught by full-time faculty showed that the sample mean course GPA was 2.71 with a sample standard deviation of 0.63, whereas a sample of 88 courses taught by part-time faculty showed a sample mean course GPA of 2.86 with a sample standard deviation of 0.49. Does it appear that the true average course GPA for full-time faculty lead courses differs from that of part-time faculty lead courses? Conduct a hypothesis test using a significance level of a = 0.01.
