Question
In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations). Also, the design provided the following information. SSTR = 200 (Sum of Squares Due to Treatments) SST = 800 (Total Sum of Squares) If at a 5% level of significance, we want to determine whether or not the means of the five populations are equal, the critical value of F is Select one: a. 19.48. b. 2.53 c. 5.69 d. 4.98. The contents of a sample of 26 cans of apple juice showed a standard deviation of 06 ounces. We are interested in testing whether the variance of the population is significantly more than .003. At the .05 level of significance, the null hypothesis Select one:Explanation / Answer
from above given data:
hence critical value F=2.53
