The prices of hot dogs and soft drinks at 5 randomly selected Major League Baseball stadiums are shown in Table 37.

Let x be the price of a hotdog and y be the price of a soft drink, both in dollars, at a Major League Baseball stadium.
a. Construct as catterplot, treating x as the explanatory variable.
b. Find the linear regression equation.
c. The equation of the line that contains the data points (5.50, 5.75) and (3.50, 2.50) is = 1.63x - 3.19. Graph the equation and the regression equation on the same scatterplot. Describe how well each line fits the data points.
d. Find the sum of squared residuals for the linear model = 1.63x - 3.19.
e. Find the sum of squared residuals for the regression line.
f. Compare the results you found in parts (d) and (e) and explain why your comparison is not surprising.
