What is the correlation coefficient with the following data points:
(1,6), (3,2), (7,5), (6,2)?

a.) 0.27
b.) -0.27
c.) 0.28
d.) -0.28

Option D → -0.28                                                                                Step-by-step explanation:

Given : Data points : (1,6), (3,2), (7,5), (6,2)

To find : What is the correlation coefficient with the following data points?

Solution :

Let x= 1,3,7,6

And y=6,2,5,2

N is the number of points i.e, N=4

The formula of correlation coefficient is

Now, we find term by term

Substitute all the values in the formula,

Therefore, The correlation coefficient is -0.28.

So, Option D is correct.

answer: sine

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
