It was hypothesized that the number of bottles of craft 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
Compute a 95% prediction interval and a 95% confidence interval for the number of bottles of beer sold when the average cost of a meal is $27.
