graduation rate is one measure used to compare colleges in national publications. one such publication compared semester tuition against graduation rate, defined as the percentage of students who graduate within four years. the value of r for the scatterplot is 0.856. which of the following is an appropriate summary of the scatterplot? there is no relationship between tuition and graduation rate. colleges with lower tuition tend to have higher graduation rates. colleges with higher tuition tend to have higher graduation rates. there is a weak, positive relationship between tuition and graduation rate.

Answer

Brief Explanations:

  • The correlation coefficient ( r = 0.856 ) is close to ( 1 ), indicating a strong positive linear relationship.
  • In a scatter - plot with a positive relationship, as one variable (tuition) increases, the other variable (graduation rate) also tends to increase.

Answer:

Colleges with higher tuition tend to have higher graduation rates.
