Explanation / Answer
The p-value for F test is: 0.1330
Since p-value is greater than 0.05 so we fail to reject the null hypothesis that there is no difference in the mean number of months before a raise was granted among the four CPA firms.
-------------
The critical value of F for 0.01 signficance level: 6.552
If F > 6.552, reject H0
The critical value of F for 0.05 signficance level: 3.708
If F > 3.708, reject H0
