What is the relationship between the price of crude oil and the price you pay at the pump for gasoline? The accompanying table shows the prices of crude oil and the price you pay at the pump for 24 consecutive months. Complete parts (a) through (h) below. Click the icon to view the data table. Click the icon to view a table of critical values of the Durbin-Watson statistic. a. Construct a scatter plot with the crude oil cost (in dollars) on the horizontal axis and the gasoline cost (in dollars per gallon) on the vertical axis. Choose the correct graph below. O A. Gasoline ($/gal) A 6- 5- 4- 3- 60 70 80 90 Crude Oil ($) B. Gasoline ($/gal) 5- 4- 3- 60 70 80 90 Crude Oil ($) C. Gasoline ($/gal) 5 4- 3- 2- 1- 60 70 80 90 Crude Oil ($) O D. = -6.054 + (0.105) X₁ (Round to three decimal places as needed.) c. Interpret the meaning of the slope, b₁, in this problem. Choose the correct answer below. Gasoline ($/gal) 5- 4- 3- 2- 1- 60 70 80 90 Crude Oil ($) b. Use the least-squares method to develop a simple linear regression equation to predict the gasoline prices using the average crude oil cost as the independen variable. OA. A slope of b₁ indicates no linear relationship between the variables. OB. The slope, b₁, implies that for each increase of 1 unit of crude oil cost, the gasoline cost is expected to change by the value of b₁. OC. A slope of b₁ indicates a moderate linear relationship between the variables. O D. The slope, b₁, implies that the average cost of crude oil is about b₁ dollars.
