State the total degrees of freedom for the following t-tests. (if you need to use [infinity], enter infinity.)
(a) n = 21 for a one-independent sample t-test
(b) df1 = 13, n2 = 22 for a two-independent sample t-test
(c) critical value = 63.657 for a two-tailed test, α = 0.01
(d) critical value = 1.645 for a one-tailed test, α = 0.05

$32,660

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
