To find the critical value of F at the 0.05 level of significance, we need to use the F-distribution table with degrees of freedom (df1 = n1 - 1 and df2 = n2 - 1) equal to 9 for both professors. Looking at the table, we can see that the critical value of F at the 0.05 level of significance and with df1 = 9 and df2 = 9 is 3.18. Therefore, the answer is C.
