Answer:

B. Two dependent samples are compared

Step-by-step explanation:

We use it when we are comparing Two dependent samples. The paired t-test can be likened to the repeated measures ANOVA test. Both of these two test are useful when comparing how a static group does in different test conditions.

But the difference between these two are:

We use the paired t-test if the explanatory variable has two levels.

While the Repeated measures ANOVA is used when the explanatory variable has greater than two levels.

Write (2 4) and (6 16) in the form y=mx+b
Lena [83]

Answer:

y = 3x-2

Step-by-step explanation:

We can find the slope using the formula

m = (y2-y1)/(x2-x1)

  = (16-4)/(6-2)

  =12/4

 =3

We then use the point slope form of a line

y-y1= m(x-x1)

y-4 = 3(x-2)

Distribute the 3

y-4= 3x-6

Add 4 to each side

y-4+4 = 3x-6+4

y = 3x-2

This is in slope intercept form
