Which value is the best estimate of the correlation
coefficient for the variables in the scatter plot?
a. -0.85
b. -0.3
c. 0.19
d. 0.92

Option D

D. 0.92

Step-by-step explanation:

The correlation coefficient "r" is a number between -1 and 1 that indicates how related are two variables X and Y.

The stronger the nearest correlation is, the value of r a -1 or a 1.

A negative correlation indicates that when X increases Y decreases.

A positive correlation indicates that when X increases Y increases.

A correlation close to zero implies that there is very little correlation of the variables. When this happens, the points are scattered in the graph.

In this case you can see in the graph that the points are not scattered, but aligned. You can also observe that when X increases Y increases also.

This allows us to conclude that the correlation is strong and positive. Therefore the correct option is option D.

9 x 8 divided by (5-3)=36

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
