The operations manager at a chemical company that produces insecticide for use in commercial applications is attempting to set a safety stock level for a key ingredient that is used in their most powerful product. She believes that demand during lead time for this ingredient is normally distributed based on past data. In addition, she believes that future use is accurately depicted by these historical demand-duringlead-time data (in gallons): 55, 75, 75, 70, 80, 60, 50, 70, 60, and 85. She estimates the standard deviation of demand during the lead time to be 8.5 gallons.

a. What is the average demand during the lead time for this key ingredient?
b. What is the safety stock they need to provide a 95% service level?
c. What is the order point the company should use?

The hawthorne works was a large western electric factory with 45,000 employees. during the 1920s and 1930s, hawthorne works was the site of some well-known industrial studies. in one of the studies, researchers investigated the impact of different working conditions on worker productivity. prior to the start of the study, researchers secretly measured workers' productivity for several weeks. then researchers chose two workers, who then chose their own teams. the teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). for each of these changes in working conditions, the researchers measured the effect on productivity. for some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity.why did the researchers secretly measure the workers' productivity before creating the two treatment groups? a, to create similar treatment groups so that a cause-and-effect relationship could be establishedb, to draw conclusions about the productivity of all workers in the plant based on the test groupsc, to directly control for confounding variablesd, to provide a baseline for measuring worker productivity

Amonopolist’s inverse demand function is p = 150 – 3q. the company produces output at two facilities; the marginal cost of producing at facility 1 is mc1(q1) = 6q1, and the marginal cost of producing at facility 2 is mc2(q2) = 2q2.a. provide the equation for the monopolist’s marginal revenue function. (hint: recall that q1 + q2 = q.)mr(q) = 150 - 6 q1 - 3 q2b. determine the profit-maximizing level of output for each facility.output for facility 1: output for facility 2: c. determine the profit-maximizing price.$

To assess the risk and return involved in a purchase decision, which practical questions should a potential buyer ask? select three options. what can go wrong? what are the alternatives? how will it affect my status in society? what is the likely return? is the risk worth the return?
