Given below are the analysis of variance results from a Minitab display. Assume that you want to use a 0.05 significance level in testing the null hypothesis that the different samples come from populations with the same mean. What can you conclude about the equality of the population means? Source DF s MS F Factor 3 30 10.00 1.6 0.264 Error 50 6.25 Total 11 80 O A.
