Question

An experiment has a single factor with seven groups and three values in each group In determining the among-group variation, there are 6 degrees of freedom. In determining the within-group variation, there are 14 degrees of freedom. In determining the total variation, there are 20 degrees of freedom. Also, note that SSA = 84, SSW = 98, SST = 182, MSA= 14, MSW = 7, and F_STAT = 2, Complete parts (a) through (d). a. Construct the ANOVA summary table and fill in all values in the table. b. At the 0.05 level of significance, what is the upper-tail critical value from the F distribution? F_0.05 = c. State the decision rule for testing the null hypothesis that all seven groups have equal population means. Reject H_0 if d. What is your statistical decision? Since F_STAT is than the upper-tail critical value, H_0. There is evidence to conclude there is a difference in the population means for the seven groups.

Explanation / Answer

b)at 0.05 level critical vlaue =2.8477

c) Reject Ho if F stat>2.8477

d)F stat is less then .......retain Ho. There is no evidence ,,,,,,,,,,,

degree of freedom Sum of square Mean square F among groups 6 84 14 2 with in groups 14 98 7 total 20 182
