MAT 150 Exam Questions and Answers | Latest 2023/2024 | Straighterline (GRADED). What is the critical value of F at the 5% level of significance? Select one: a. 3.29 b. 3.68 c. 3.59 d. 3.20 Feedback There are three treatments and a total of 18 observations, so k = 3 and n = 18. The treatment degrees of freedom are k - 1 = 3 - 1 = 2, and the error degrees of freedom are n - k = 18 - 3 = 15. Therefore, the F-distribution would have 2 degrees of freedom in the numerator and 15 degrees of ...
