Use the following scatterplot to answer the question below.

A scatterplot has a horizontal axis labeled "x" with values from 30 to 110 and a vertical axis labeled "y" with values from 30 to 110. The scatterplot has 15 points. A pattern goes up and right from (49, 43) to (94, 76). The points are as follows.

  • (49, 50)
  • (59, 60)
  • (65, 43)
  • (65, 71)
  • (66, 51)
  • (66, 76)
  • (67, 69)
  • (70, 65)
  • (71, 75)
  • (75, 59)
  • (75, 65)
  • (75, 76)
  • (80, 60)
  • (84, 73)
  • (94, 74)

Which correlation coefficient would be the most accurate?

r = −0.30

r = −0.70

    

r = 0.70

r = 0.30
