12. For each of the following F values, indicate whether the F is statistically significant at the specified alpha level: a. F = 3.80, df = 4, 40 a = 0.01 b. F = 3.85, df = 3, 27, a = 0.05 c. F = 4.19, df = 2, 150, a = 0.01 d. F = 2.39, df = 2, 250, a = 0.05 Solution a. F= 0.0103 (check F table) is larger than a=0.01, F is not statistically significant b. F= 0.0205 (check F table) is less than a=0.05, F is statistically significant c. F=0.017 (check F table) is larger than a=0.01, F is not statistically significant d. F= 0.0937 (check F table) is larger than a=0.05, F is not statistically significant.
