PROBLEMS 1. The relationship between advertising budget and the number of cars sold can be described by the regression line y = 9.107 + .0582x. If the actual data is given below, calculate the standard error of estimate. Advertising Budget 23 46 Cars Sold 9.6 11.3 60 54 12.8 9.8 a) Using another method, another regression line (y = 10 +.06x) was constructed. The standard error of estimate of that line is 1.5. Which of the two lines is a better fit for the data?
