Question

*Can someone please help me out with this one?*

A nutritionist collects data from 25 popular breakfast cereals. For each cereal, the number of calories per serving is
plotted on the x-axis against the number of milligrams of sodium on the y-axis. The value of , for the resulting
scatterplot is 0.83.
How would the value of the correlation coefficient change if sodium was plotted on the x-axis
and calories plotted on the y-axis?

A.The value of r would increase

B.The value of r would not change

C.The value of r would change to -0 83.

D.The value of r could increase or decrease, depending of the strength of the new relationship.

Answer 1

Either A - the value of r would increase or B- the value of r would not change.

Answer 2

B) The value of r would not change

Explanation:

If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.
