Palace s manager, Joe Felan, suspects that demand for mocha latte
coffees depends on the price being charged. Based on historical
observations, Joe has gathered the following data, which show the
numbers of these coffees sold over six different price values: Price /
Number Sold. $2.70 / 760, $3.50 / 510, $2.00 / 980, $4.20 / 250, $3.10 /
320, $4.05 / 480. Using these data, how many mocha latte coffees would
forecast to be sold according to simple linear regression if the price
per cup were $2.80?
