Question

A department of transportation's study on driving speed and miles per gallon for midsize automobiles resulted in the following data.

Speed (Miles per Hour)	30	50	40	55	30	25	60	25	50	55
Miles per Gallon	29	26	24	22	29	33	22	36	25	24

Compute the sample correlation coefficient. (Round your answer to two decimal places.)

Interpret the sample correlation coefficient.

There is relationship between the driving speed and miles per gallon. For driving speed between 25 and 60 miles per hour, higher speeds are associated with miles per gallon.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
