I give good rate to correct answers ! Question #4 / 20 The Cadet is a popular model of sport utility vehicle, known for its relatively high resale value. The bivariate data given below were taken from a sample of fifteen Cadets, each bought new two years ago, and each sold used within the past month. For each Cadet in the sample, we have listed both the mileage x (in thousands of miles) that the Cadet had on its odometer at the time it was sold used and the price y (in thousands of dollars) at which the Cadet was sold used. With the aim of predicting the used selling price from the number of miles driven, we might examine the least-squares regression line, y-41.65-0.48r. This line is shown in the scatter plot in Figure 1 Mileage, xX (in thousands) (in thousands of 21.0 24.5 34.3 25.7 26.6 29.4 27.5 23.1 37.5 31.5 26.7 25.7 27.2 30.7 27.9 30.0 31.1 23.0 40-+ 35 30

Explanation / Answer

1) greater than the means of mileges

2) Decrease because coefficient of x is negative

3) 30.7

4) y = 41.65-0.48*26.6 = 28.9
