Question

engine production
if a good linear model for the data set is determined using technology, which phrase most likely describes the value of the correlation coefficient, r?
negative and close to -1
positive but not close to 1
positive and close to 1
negative but not close to -1

Explanation:

The scatter plot shows that as the year (x-axis) increases, the number of engines produced (y-axis) consistently increases, indicating a positive correlation. The points lie very close to a straight line, meaning the linear relationship is strong, so the correlation coefficient is close to 1.

Answer:

positive and close to 1
