Using these assets, you have isolated the three investment alternatives shown in the following table.
Alternative investments 1- 100% of asset F
Alternative 2 50% of asset F and 50% of asset G
Alternative 3 50% of asset F and 50% of asset H
a. Calculate the expected return over the 4-year period for each of the three alternatives
b. Calculate the standard deviation of returns over the 4-year period for each of the three alternatives
c. Use your findings in parts a and b to calculate the coefficient of variation for each of the three alternatives
d. On the basis of your findings, which of the three investment alternatives do you recommend? why?

Anew equipment has been proposed by engineers to increase the productivity of a certain manual welding operation. the investment cost is $25,000, and the equipment will have a market value of $5,000 at the end of a study period of five years. increased productivity attributable to the equipment will amount to $10,000 per year after operating costs have been subtracted from the revenue generated by the additional production. if marr is 10%, is investing in this equipment feasible? use annual worth method.

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
