1. A study by M. Chen et al. titled "Heat Stress Evaluation and Worker Fatigue in a Steel Plant"(American Industrial Hygiene Association, Vol. 64, pp. 352-359) assessed fatigue in steel-plantworkers due to heat stress. A random sample of 29 casting workers had a mean post-work heartrate of 78.3 beats per minute (bpm) with a standard deviation of 11.2 bpm. At the 5%significance level, do the data provide sufficient evidence to conclude that the mean post-workheart rate for casting workers exceeds the normal resting heart rate of 72 bpm? You may assumethat the conditions for normality are satisfied.

/transcript Call centers typically have high turnover. The director of human resources for a large bank has compiled data on about 70 former employees at one of the bank's call centers. The accompanying table shows this data. In writing an article about call center working conditions, a reporter has claimed that the average tenure is no more than two years. Formulate and test a hypothesis using these data to determine if this claim can be disputed. Use a level of significance of 0.05. Click the icon to view the call center data.

Medication used to treat a certain condition is aministered by syringe. The target dose ina particular application is 10 milligrams. Because of the variations in the syringe, in reading the scale, and in mixing the fluid suspension, the actual dose administered is normally distrubuted with a mean of 10 milligreams and a standard deviation of 1.6 milligrams. What is the probablility of that the dose administered is between 9 and 11.5 milligrams? Find the 98th percentile of the adninisterd dose. If clinical overdose is defined as a dose larger that 15 milligrams, what is the probablility that a patient will receive an overdose.
