In 2009 the number of vehicle sales in the United States was 10,602 thousand and in 2013 it was 16,984 thousand.
a. Determine the average rate of change (slope) from 2009 to 2013.
b. Using the slope from part a., if x is the number of years since 2009 and f (x) is the number of vehicles sold, find the equation of the line through these two points.
c. Assuming f (x) is a linear function, use the equation from part b. to predict the number of vehicles sold in 2016 (in thousands).

The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 41 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance. What are we testing in this problem?...
