Answer 1

The F test statistic here is computed as:

F* 8.82 10.22 = 0.7443 S2

For n₁ - 1, n₂ - 1 = 47 and 25 degrees of freedom, we get the p-value from F distribution tables as:

p= P(F47,25 < 0.7443) = 0.188

Therefore 0.188 is the required p-value here.

This can be computed using EXCEL as:
=F.DIST(0.744329104190696,47,25,TRUE)
