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 39 56 30 24 61 24 51 56
Miles per Gallon 29 24 25 22 30 33 21 35 25 25

Compute the sample correlation coefficient (to  2 decimals and enter negative value as negative number).

 

What can you conclude, based on your computation of the sample correlation coefficient?

-strong postive relationship

-moderate  postive relationship

-neither postive or negative relationship

-strong negative relationship

-moderate negative relationship

 

Select the correct interpretation for the sample correlation coefficient.

(i) For driving speeds between 24  and  61 miles per hour, higher speeds are associated with higher miles per gallon.

(ii) For driving speeds between 24  and  61miles per hour, higher speeds are associated with lower miles per gallon.

(iii) For driving speeds between 24  and  61 miles per hour, lower speeds are associated with lower miles per gallon.

(iv) There is no relationship between driving speed and miles per gallon.
