Real wages, nominal wages, and unexpected changes in the price level Rina currently earns a wage of $12.00 per hour; in other words, the amount of her paycheck each week is $12.00 per hour times the number of hours she works. Suppose the price of milk is $2.40 per gallon; in this case, Rina's wage, in terms of the amount of milk she can buy with her paycheck, is gallons of milk per hour. When workers and firms negotiate compensation packages, they have expectations about the price level (and changes in the price level) and agree on a wage with those expectations in mind. If the price level turns out to be lower than expected, a worker's wage is than both the worker and employer expected when they agreed to the wage. Rina and her employer both expected inflation to be 3% between 2012 and 2013, so they agreed, in a two-year contract, that she would earn $12.00 per hour in 2012 and $12.36 per hour in 2013. However, suppose inflation between 2012 and 2013 actually turned out to be 2%, not 3%. For example, suppose the price of milk rose from $2.40 per gallon to $2.45 per gallon. This means that between 2012 and 2013, Rina's nominal wage by % , and her real wage by approximately .

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

Q3. loral corporation manufactures parts for an aircraft company. it uses a computerized numerical controlled (cnc) machining center to produce a specific part that has a design (nominal) target of 1.275 inches with tolerances of ± 0.020 inch. the cnc process that manufactures these parts has a mean of 1.285 inches and a standard deviation of 0.005 inch. compute the process capability ratio and process capability index, and comment on the overall capability of the process to meet the design specifications.
