Speedlimit(mph)

Deathrate

A scatterplot with horizontal axis labeled "Speed limit (miles per hour)" from 50 to 80 in increments of 1 and vertical axis labeled "Death rate" from 0 to 6 plus in increments of 1 contains the following 10 plotted points: (54, 2.9); (54, 3.2); (54, 3.3); (69, 3.4); (54, 4.0); (59, 4.2); (54, 4.6); (64, 4.8); (59, 5.0); (74, 6.0).

This is the correct answer.

A scatterplot with horizontal axis labeled "Death rate" from 50 to 80 in increments of 1 and vertical axis labeled "Speed limit (miles per hour)" from 0 to 6 plus in increments of 1 contains the following 10 plotted points: (54, 2.9); (54, 3.2); (54, 3.3); (69, 3.4); (54, 4.0); (59, 4.2); (54, 4.6); (64, 4.8); (59, 5.0); (74, 6.0).

Your answer is not correct.

b. Calculate the correlation coefficient of the data. Briefly characterize the correlation in words(for example, moderate positivecorrelation, weak negativecorrelation).

0.59 (Round to two decimal places asneeded.)

Characterize the correlation in words.

There is a moderate positive

correlation.
