Ans. 20. Calculate the F ratio. a. 0.51 b. 0.94 C. 2.43 d. 3.76 Ans. 21. Let's say (instead of your calculations for number 19 and number 20 above) you found: What would your P-value be? F = 4.2, df (numerator) = 4, df (denominator) = 8 (If you use the table in the book, choose the value below that fits in the range you find). a. 0.381 b. 0.040 C. 0.804 d. 0.086 ovods TOM 20 nevis Ans. 22. Let's say you fail to reject the Null hypothesis for this problem. Choose the best conclusion. a. At a = 0.05, the data indicate the population means for the three states differ. b. At a = 0.01, the data indicate the population means for the three states differ. c. At a = 0.05, the data indicate the population means for the three states are the same. d. At a = 0.01, the data indicate the population means for the three states are the same. Ans.
