(7 points) Suppose a recent random sample of employees nationwide that have a 401(k) retirement plan found that 20% of them had borrowed against it in the last year. A local company is interested in assessing whether this proportion adequately describes the borrowing behavior of their employees. They take a random sample of 150 employees and find that 17 had borrowed from their plan. Conduct a hypothesis test to investigate whether the borrowing rate at this company is less than...
Last year, 36.6 % of all employees at a large company enrolled in at least one wellness class at the company's site. A survey is sent out to a sample employees at the start of the new fiscal year to see if a greater percentage is planning to take a wellness class this year.

In order to shrink its labor force, a large company (such as IBM) is considering offering an early retirement package to its employees who are over fifty-five and who have been on the payroll at least ten years.

A random sample of 100 eligible employees indicates that 30 of them would accept the early retirement package, if it were offered. Using...
