are larger in absolute value than the critical values.

are smaller in absolute value than the critical values.

are the same in absolute value than the critical values.

Question 2

Based on these results, t (92) = -.67, p = .41, d = -.10. The math scores of males (M = 31.54, SD = 5.16, n = 29) on and females were compared (M = 32.46, SD = 4.96, n = 65). What can be concluded based on these results?

Males (M = 31.54, SD = 5.16, n = 29) on average score statistically significantly higher than females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement.

Males (M = 31.54, SD = 5.16, n = 29) on average do not statistically significantly differ from females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement

Males (M = 31.54, SD = 5.16, n = 29) on average score statistically significantly lower than females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement.
