Use the following information for following questions .
A random sample of 100 cars was taken and data were recorded on the miles per gallon (mpg) in the city
and on the highway. The mean city mpg was 28 with a standard deviation of 9.2. The mean highway mpg
was 35 with a standard deviation of 8.6. The correlation coefficient between city mpg and highway mpg is
-Determine the correct value of the slope for the linear model that predicts highway mpg from city mpg and interpret it in context.

A) The slope is 0.888.For every one mpg increase in city mpg, the highway mpg is predicted to increase by 0.888.
B) The slope is 0.888.For every one mpg increase in highway mpg, the city mpg is predicted to increase by 0.888.
C) The slope is 1.016.For every one mpg increase in city mpg, the highway mpg is predicted to increase by 1.016.
D) The slope is 1.016.For every one mpg increase in highway mpg, the city mpg is predicted to increase by 1.016.
