Let’s sum up some basic facts of U. S. economic history with numbers: a. First, let's measure the size of the Great Depression: Year Real GDP Price level 1929 (Peak) $323 Billion 33 1933 (trough) $206 Billion 24 Calculate the percent change in real GDP and the percent change in the price level 1929 to 1933. First, calculate the total change, and then divide it by the number of years to get the more typical measure of "percent per year." Round your answers to the nearest percent. (Note: This is four full years, not three or five.)

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
