Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 40 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that o = 7.10 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level? (Give your answer to two decimal places.)

The average age of licensed drivers in a county is µ = 42.6, s= 10, and the distribution is approximately normal. A county police officer was interested in whether the average age of drivers receiving parking tickets differed from the average age of the driving population. She obtained a sample of N = 100 drivers receiving parking tickets. The average age of these drivers was M = 40.6. Say the researcher wants to determine whether this group differs from the population of drivers in the county. Use an alpha level of 0.05 (zcrit=1.96 (two-tailed test)/ zcrit=1.65 (one-tailed test)). 31. What are the null and alternative hypotheses? 32. What is the z statistic associated with this case? 33. Using the z critical information available, draw a normal distribution and fill in the observed z statistic, z critical and make the decision for the hypotheses based on the available information.
