Question 1

Consider the data set shown below. Find the estimate of the y-intercept of the least squares regression line.



◦ 1.5
◦ 0.9003
◦ 0.94643
◦ 1.49045

Question 2

In a comprehensive road test for new car models, one variable measured is the time it takes the car to accelerate from 0 to 60 miles per hour. To model acceleration time, a regression analysis is conducted on a random sample of 129 new cars.

TIME60: y = Elapsed time (in seconds) from 0 mph to 60 mph
MAX: x = Maximum speed attained (miles per hour)

The simple linear model E(y) = β0 + β1x was fit to the data. Computer printouts for the analysis are given below:

NWEIGHTED LEAST SQUARES LINEAR REGRESSION OF TIME60







CASES INCLUDED 129   MISSING CASES 0

Find and interpret the estimate 1 in the printout above.
