To find the critical value of F at the 0.05 level of significance, we need to use an F-distribution table with degrees of freedom (df) of 9 and 9 (n1-1 and n2-1). Looking at the table, the value closest to 0.05 and with df1=9 and df2=9 is 3.18. Therefore, the critical value of F at the 0.05 level of significance is 3.18.
