For which set of data will the scatter plot represent a positive linear association between x and y?

Select one:
a. Set A
b. Set B
c. Set C
d. Set D

Respuesta :

Answer:

Set B.

Step-by-step explanation:

Not A or C: as x goes up, y goes down. :(

D is correct, but not the best because B's is more clear, as when visualizing the graphs, B's makes a perfect line, as where in D, it is bumpier.
