The Results of an Experiment Comparing the Cycle Lengths of Three

The results of an experiment comparing the cycle lengths of three different brands of washing machines (N=33) indicated an overall mean square error of 2.58.The researcher believes that the brands 1 and 2 may be the most different as they have mean cycles of 31.8 (n=12) and 35.9 (n=10) .Using an alpha of 0.05, would the research find evidence of a significant difference in these brands?

A) Yes, as the difference in the means is larger than the critical value
B) No, as the critical value is smaller than the overall sample size
C) Yes, as the difference in the means is smaller than the critical value
D) No, as the difference in the means is larger than the critical value
E) No, as the difference in the means is smaller than the critical value
