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? Group of answer choices To create similar treatment groups so that a cause-and-effect relationship could be established To provide a baseline for measuring worker productivity To directly control for confounding variables

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non. conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non. conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
