A frequent flyer was interested in the relationship between dollars spent on flying and the distance flown. She randomly sampled 20 frequent flyers of a certain airline. She collected the number of miles flown in the previous year and the total amount of money the flyer spent. A regression line of distance flown on money spent was fit to the data, and the intercept and slope were calculated to be a 24,000 and b = 10. One of the randomly sampled frequent flyers was found to have spent $2500 and to have flown 53,000 miles. The residual for this observation is 4000. -8000. -16,000. 12,000. =
