It was hypothesized that the number of bottles of an imported premium beer sold per evening in the restaurants of a city depends linearly on the average costs of meals in the restaurants. The following results were obtained for a sample of n = 17 restaurants of approximately equal size where
y = number of bottles sold per evening
x = average cost, in dollars, of a meal
a. Find the sample regression line.
b. Interpret the slope of the sample regression line.
c. Is it possible to provide a meaningful interpretation of the constant in the sample regression at the end with equation? Explain.
