There is only one payroll training tax in North America. The Quebec government program that forces employers to spend 1 percent of payroll on training may not have the intended consequences of increasing training investments in employees. Using data from a Statistics Canada survey, Alan Saks of the University of Toronto and Robert Haccoun of the Université de Montréal matched Quebec employers with Ontario employers and found that there were no differences in amounts spent on training. The paperwork is so cumbersome that many employers prefer to pay the 1 percent tax rather than go through the thick guidebooks necessary to report the training. There are many other mandatory training programs across Canada. In addition to legal requirements in posting information on employment standards, occupational health and safety, accessibility, pay equity plans, workplace violence policies, among others, legislation require organizations to have formal training programs in place.

Mercury, Incorporated, produces cell phones at its plant in Texas. In recent years, the company’s market share has been eroded by stiff competition from overseas. Price and product quality are the two key areas in which companies compete in this market. A year ago, the company’s cell phones had been ranked low in product quality in a consumer survey. Shocked by this result, Jorge Gomez, Mercury’s president, initiated an intense effort to improve product quality. Gomez set up a task force to implement a formal quality improvement program. Included on this task force were representatives from the Engineering, Marketing, Customer Service, Production, and Accounting departments. The broad representation was needed because Gomez believed that this was a companywide program and that all employees should share the responsibility for its success. After the first meeting of the task force, Holly Elsoe, manager of the Marketing Department, asked John Tran, production manager, what he thought…
A toy manufacturer wants to see how long, on average, a new toy captures children's attention. He tests 17 children selected at random and finds that their mean attention span is 27 minutes with a standard deviation of 5 minutes. If we assume that attention spans are normally distributed, find a 90% confidence interval for the mean attention span of children playing with this new toy. Give the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: Upper limit:
