Find critical value ti 84.

It is possible to formulate the F-test to see if a sloping linear regression produces a significantly better result than no regression. Assume there is a table with two critical values, and one of the F-values is at the p = 0.05 level of significance. The p = 0.01 level of significance is the second critical value of F. Calculate your F-ratio.
