Problem 2
Coffee Palace’s manager, Joe Felan, suspect that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Joe has gathered the following data, which shows 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 be forecast to be sold according to simple linear regression if the price per cup were $2.80?

Module 3 Exercise

Complete the following Location Strategy problem:

Our main distribution center in Phoenix, AZ is due to be replaced with a much larger, more modern facility that can handle the tremendous needs that have developed with the city’s growth. Fresh produce travels to the seven store locations several times a day making site selection critical for efficient distribution. Using the data in the following table, determine the map coordinates for the proposed new distribution center.
