A manager intends to order a new machine and must now decide on the number of spare parts to order along with the machine. The parts cost $496 each and have no salvage value. The manager has compiled the frequency distribution for the probable usage of spare parts:7 spare parts with frequency 0.05;8 spare parts with frequency 0.23;9 spare parts with frequency 0.08;10 spare parts with frequency 0.07; and 11 spare parts with frequency 0.57. For what range of shortage costs would stocking 9 spare parts constitute an optimal decision ? a. Between 231.5and 334.8 b. Between 192.9and 279 c. Between 289.3and 418.5 d. Between 96.44and 139.5

10 Dr. Lillian Fok, a New Orleans psychologist, specializes in treating patients who are agoraphobic (i.e., afraid to leave their homes). The following table indicates how many patients Dr. Fokh each year for the past 10 years. It also indicates what the robbery rate was in New Orleans during the same year: ! 1 F1 A 1 option Year Number of Patients Robbery Rate per 1,000 Population The simple linear regression equation that shows the best relationship between the number of patients and the robbery rate is (round your responses to three decimal places): ŷ=0+0x N @ 2 W S X command A where y Number of Patients and x = Robbery Rate. In year 11, if the robbery rate increases to 133.40, using trend analysis, the number of patients Dr. Fok will see = patients (round your response to two decimal places). In year 11, if the robbery rate decreases to 90.6, using trend analysis, the number of patients Dr. Fok will see = patients (round your response to two decimal places). #3 80 F3 E D $ 4 C 888…

Café 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: Price $2.50 $3.40 $1.90 $4.10 $3.20 $4.00 Number Sold 770 510 975 240 315 475 Using simple linear regression and given that the price per cup is $1.75, the forecasted demand for mocha latte coffees will be (enter your response rounded to one decimal place). cups
