To determine the critical value of Fisher-Snedecor (also known as the F-test), we need to identify the correct value from the provided table that corresponds to the given significance level ( ) and degrees of freedom ( and ).Given:- Significance level ( ) = 0.05- Degrees of freedom for the numerator ( ) = 5- Degrees of freedom for the denominator ( ) = 4We need to find the critical value for , which corresponds to the upper tail of the F-distribution.From the provided table, we look for the value in the row where and , and then select the appropriate value for .The table entry for and at is 7.15.Therefore, the correct answer is:7.15
