Caf Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Using simple linear regression and given that the price per cup is $1.85, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place). Sales of tablet computers at Marika Gonzalez's electronics store in Washington, D.C., over the past 10 weeks are shown in the table below: DW a) The forecast for weeks 2 through 10 using exponential smoothing with =0.60 and a week 1 initial forecast of 21.0 are (round your responses to two decimal places): The Carbondale Hospital is considering the purchase of a new ambulance.

The following table indicates how many patients Dr. Fok has seen each year for the past 10 years. It also indicates what the robbery rate was in New Orleans during the same year: The simple linear regression equation that shows the best relationship between the number of patients and year is (round your responses to three decimal places): y^=+x where y^= Dependent Variable and x= Independent Variable. Mark Gershon, owner of a musical instrument distributorship, thinks that demand for guitars may be related to the number of television appearances by the popular group Maroon 5 during the previous month.
