The data indicate _________ of variance; therefore, we should use the output under Equal Variances __________

A researcher compared the GPA of traditional (aged 18-22) and nontraditional (aged 23 or older) students. Table 10-1 GROUP 1 = Aged 18-22 GROUP 2 = Aged 23 or older Variable = Grade point average GROUP N Mean SD Standard Error GROUP 1 15 2.95 0.556 0.143 GROUP 2 15 3.08 0.524 0.135 PM test F = 0.225 p = 0.639 Equal Variances Assumed = -0.68 df = 28 p = 0.509 Equal Variances Not Assumed = -0.68 df = 27.90 p = 0.509 What statistical analysis is conducted? How many participants were in the study? The mean GPA for traditionally-aged students was The mean GPA for nontraditionallyaged students was The data indicate of variance; therefore, we should use the output under Equal Variances The p-value is ' m-AWMrI um The difference in means signicant; therefore, we conclude that the difference between the two means is due to
