  147 152 126
  165 124 138
  145 140 140
  150 152 140

Sample mean

 152.4 143.2 134.4

Sample variance

 63.8 139.2 46.8

(A). What is the F test statistics value?

(B). Compute the mean squares due to error.

(C). At the α = 0.01, test whether the means for the three treatments are equal.

  1. Using F table, what is the most possible range of values of the p-value?

[Multiple choice with single answer]

(a) 0.025<p-value<0.1

(b) 0.01<p-value<0.05

(c) 0.01<p-value<0.025

(d) 0.025<p-value<0.05

(e) 0.05<p-value<0.1

(f) None of the above
