Statistics
Traditionally, the psychology department had offered the Psychological Statistics course in the face-to-face (F2F) instruction format. Final exam scores for all students taking the Psychological Statistics class in this format are normally distributed with u = 71 with o = 12. Since 2020, the department has changed its curriculum by introducing an online course offering. To evaluate the effects of this change, a random sample of 36 students who registered for Psychological Statistics was placed in the online version of the course. At the end of the semester, the 36 students took the final exam identical to the one used in course in the F2F format. The mean exam score for the sample was 75. Is there enough evidence that the performance on the final exam in the online version of the course was different from the F2F class? Conduct the 4-step hypothesis test (two- tailed) with the alpha level of .05. Based on the statistical evidence, can you claim that the performance on the final exam in the online version of the course is different from the performance in the F2F class? Yes O No
