What are the F critical values below for α = 0.05?

a) df = 4, 14:
b) df = 9, 6:
c) df = 5, 15:

Expert Solution

Random Variable F ~ F_4,14

F critical value for =0.05 is denoted by F_0.05;4,14

This implies :- P(FF_0.05;4,14) = 0.05 F_0.05;4,14 = 3.11225

[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,4,14) in Excel 07. ]

Random Variable F ~ F_9,6

F critical value for =0.05 is denoted by F_0.05;9,6

This implies :- P(FF_0.05;9,6) = 0.05 F_0.05;9,6 = 4.099016

[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,9,6) in Excel 07. ]

Random Variable F ~ F_5,15

F critical value for =0.05 is denoted by F_0.05;5,15

This implies :- P(FF_0.05;5,15) = 0.05 F_0.05;5,15 = 2.901295

[ This value is obtained using from the F-distribution table or by using the function =FINV(0.05,5,15) in Excel 07. ]

Using R code solve Here, we look at how t critical values behave as their df (degrees of freedom) increases: a. First, what is z.05? b. Second, if you look at t.05,df (t critical values for α = .05) with df = 20, 40, 60, etc (continuing up by 20 each time), for what df does the t critical value first fall strictly within (e.g. < ) i. .05 of z.05? ii. .02 of z.05? iii. .01 of z.05? c....

Calculate the Y values corresponding to the X values given below. Find the critical values for X for the given polynomial by finding the X values among those given where the first derivative, dy/dx = 0 and/or X values where the second derivative, d¬2y/dx2 = 0. Be sure to indicate the sign (+ or -) of dy/dx and of d2y/dx2 tabled values. Using the first and second derivative tests with the information you have calculated, determine which X value(s) represent...
