Ten observations were selected from each of 3 populations and an analysis of variance was performed on the data. The following are the results:

Source of variation	Sum of squares	degrees of freedom	mean square	F
Between treatments	82.4
Within treatments (Error)	158.4
Total

A. Using alpha= .05, test to see if there is a significant difference among the means of the three populations.

B. If in part A you concluded that at least one mean is different from the others, determine which mean is different using LSD method. The three samples are (mean) X1=24.8, X2=23.4, X3=27.4.
