An experiment was run to compare three groups. The sample sizes were 28, 33, and 102, and the corresponding estimated standard deviations were 2.7, 2.6 and 4.8. A) Is it reasonable to use the assumprion of equal standard deviation when we analyze these data? Give a reason for the answer. B) Give the Values of the Variances for the three groups. C) Find the pooled variance.
