Determine the upper tail critical values of F in each of the following two-tailed tests:

a. The critical value of F when α = 0.005, n1 = 16, and n2 = 10 is

(Round to two decimal places as needed.)

b. The critical value of F when α = 0.05, n1=16, and n2 = 10 is

(Round to two decimal places as needed.)

Solutions

Expert Solution

SOLUTION

a.)

Given :

where df1 = 1st degrees of freedom = n1 - 1 = 16-1 = 15

and df2 = 2nd degrees of freedom = n2 - 2 = 10 - 1 = 9

and

-------------------------------- Calculate using F table

The upper tail crictical value of F when is equal to 6.03

b.)

Given :

where df1 = 1st degrees of freedom = n1 - 1 = 16-1 = 15

and df2 = 2nd degrees of freedom = n2 - 2 = 10 - 1 = 9

and

---------------------------------- Calculated using F table

The upper tail crictical value of F when is equal to 3.01

. All of the following are true of two-tailed tests except: A. Two-tailed tests are more “conservative”, they make rejecting the null hypothesis harder  B. Two-tailed tests are used when there is not a clear basis for predicting a result in one specific direction C. With a two-tailed test, your cutoff score will be more extreme than a one-tailed test D. A two-tailed test improves the chances that you will get a statistically significant result
