Explanation / Answer

Given:

Level of significance = 0.05

Factor Degrees of freedom = 3

Error Degrees of freedom = 56

F-critical value

Hence, F-critical value from f-table for 0.05 level of significance with factor degrees of freedom of 3 and error degrees of freedom of 56 is given as 2.769

[Note: Use Excel to get this value. In any of the empty cell in excel type =FINV(0.05,3,56) to get the above value]

Decision rule:

Reject H0 is F > 2.769
