Red Point Alloys BV produces cast bronze valves for use in offshore oil platforms. Currently, Red Point produces 1600 valves per day. The 20 workers at Red Point work from 7 a.m. until 4 p.m., with 30 minutes off for lunch and a 15-minute break during the morning work session and another at the afternoon work session Red Point is in a competitive industry and needs to increase productivity to stay competitive. They feel that a 20 percent increase is needed.
Red Point’s management believes that the 20 percent increase will not be possible without a change in working conditions, so they change work hours. The new schedule calls on workers to work from 7:30 a.m. until 4:30 p.m., during which workers can take one hour off at any time of their choosing. Obviously, the number of paid hours is the same as before, but production increases, perhaps because workers are given a bit more control over their workday. After this change, valve production increased to 1800 units per day.
a) Calculate labor productivity for the initial situation.
b) Calculate labor productivity for the hypothetical 20 percent
increase.
c) What is the productivity after the change in work rules?

Faculty members in a state university system who resign within 10 years of initial employment are entitled to receive the money paid into a retirement system, plus 4% per year. Unfortunately, experience has shown that the state is extremely slow in returning this money. Concerned about such a practice, a local teachers organization decides to investigate. After a confrontation with the teachers’ union, the state promised to make reimbursements within 60 days. Monitoring of the next 40 resignations yields an average of 61 days, with a standard deviation of 10 days.
(a) Set up the appropriate hypothesis tests for this investigation.
(b) Test the null hypothesis using an α level of 0.01, draw out a graphical representation of the test. Include critical values and test statistic value. What is your conclusion regarding the population parameter μ ( state your answer in the context of the problem).

The efficacy of a drug is dependent on a therapeutic concentration reaching its target site of action. If the too little drug is present there may be no therapeutic benefit, too much and over-dosage might occur. Describe in detail the pharmacodynamic and pharmacokinetic properties that need to be ascertained in order to use a drug properly. Your answer should include how these properties can be determined, why they are important to the functioning of a particular drug and what might go wrong if these properties are determined incorrectly.
