The price of a previously owned Malibu car depends upon factors such as model year, mileage and condition. We want to investigate the relationship between a car's mileage and sale price for 30 sales. Use Data CHEV8. Draw a scatter plot of the data and comment on the relationship between the two variables. Determine the regression equation that best describe the relationship. Interpret the slope of the regression equation. Test for a significant relationship, using a = 0.05. Show all steps Construct a 98% confidence interval for the slope. Estimate the price of a Malibu car that has been driven for 85000 miles. Would you pay this price? Construct 99% confidence interval for the average price of a Malibu car that has 85000 miles
