Kay is interested in determining whether accelerated general psychology courses result in different learning outcomes compared to general psychology courses taught during a 15-week semester. To determine the effects of time, Kay administers a surprise end-of-course exam to students in both classes and compares the means of the two groups. The mean test grade of students in the accelerated course is 55 (s= 29.25), and the mean test grade was 65 (s= 27.50) in the 15-week course. IfsM1-M2= 5.04 (equal variance between groups),s2pooled= 807.10,N1= 65,N2= 62, and alpha is set at .05, what decision should Kay reach regarding the null hypothesis?
