Part 1 Step 2

Is this a one-tailed or two-tailed test? If it is a one-tailed test, are we looking at the right or left tail? Why?

Research Question:

Did those that self-identified as heterosexual score significantly different on the Stress Subscale pre-treatment than those that self-identified as LGB+?

A sample of n = 585 college students were selected to participate in the study. In the sample, n = 370 individuals self-identified as heterosexual and n = 215 individuals self-identified as LGB+. The mean score on the stress scale for those that self-identified as heterosexual was M = 27.48 with SS = 540.25 (SD = 1.221). The mean score on the stress scale for those that self-identified as LGB+ was M = 30. 47 with SS = 1938.86 (SD = 3.01).
