Question 1 10 points Save Answer A local tire dealer wants to predict the number of tires sold each month. He believes that the number of tires sold is a linear function of the amount of money invested in advertising. He randomly selects 6 months of data consisting of tire sales (in thousands of tires) and advertising expenditures (in thousands of dollars). Based on the data set with 6 observations, the simple linear regression equation of the least squares line is y = 3 + 1x. Determine the 90 percent confidence interval for the mean value of monthly tire sales when the advertising expenditure X= 5. Distance Value = .20238 O [6.08, 9.92] O [4.24, 6.12] [3.32, 12.68] O [2.38, 14.28]
