Question

1. local authorities found that as the number of stop signs in a neighborhood increases, the average number of speeding tickets issued in the neighborhood decreases. which of the following is not a true statement? a. there is positive association between the variables. b. a scatter - plot representing the situation would have a negative slope. c. the variables seem to represent causation. d. as the value of x increases, the value of y decreases.

Explanation:

Correlation does not imply causation. Just because there is a positive association between the number of stop - signs and speeding tickets does not mean one causes the other. A scatter - plot showing a relationship is about correlation, not causation. A negative slope indicates a negative association, and a positive association means as one variable increases, the other tends to increase.

Answer:

c. The variables seem to represent causation.
