Question

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 18.24

Within Treatments(error) 158.4

Using level of significance =.05, test to see if there is a significance difference among the means of the three populations.
If in (1) you concluded that at least one mean is different from the others, determine which mean is different. The three sample means are

X₁= 24.8, X₂=23.4, and X₃=27.4.

Use Fisher’s LSD procedure and let level of significance=.05
