The physical fitness of a patient is often measured by the patient'smaximum oxygen uptake (recorded in milliliters per kilogram, ml/kg).The mean maximum oxygen uptake for cardiac patients who regularlyparticipate in sports or exercise programs was found to be 24.1, with astandard deviation of 6.30 (Adapted Physical Activity Quarterly, Oct.1997). Assume that the distribution of maximum oxygen uptake forcardiac patients who regularly participate in sports or exercise pro-grams is approximately Normal.(a) What is the probability that a cardiac patient who regularly par-ticipates in sports has a maximum oxygen uptake of at least 20ml/kg?(b) What is the probability that a cardiac patient who regularly ex-ercises has a maximum oxygen uptake of 10.5 ml/kg or lower?(c) Consider a cardiac patient with a maximum oxygen uptake of10.5. Is it likely that this patient participates regularly in sportsor exercise programs? Explain.

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 50 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 ? = 7.20 ml/kg for the distribution of blood plasma.
The annual per capita consumption of oranges (in pounds) in the United States can be approximated by a normal distribution. The mean annual per capita of oranges is 19.2 with a standard deviation of 4 pounds. what annual per capita consumption of oranges represents the 5th percentile?
The scores on a college entrance test have an approximately normal distribution with mean, µ = 84 points and a standard deviation, σ = 5 points. About 68% of the x values lie between what two values?
The antibody production of 12 male red-winged blackbirds before and after receiving testosterone implants was compared. The units for antibody levels were natural log (10-3 optical density) per minute (In(mOD/min)). The mean change in antibody production was d = 0.056, and the standard deviation was sd = 0.225 If you were assigned the task of repeating this experiment, and wanted to ensure that you could detect a mean change of 0.02 units with a probability of 0.8, then what sample size would you use? Since we are calculating n for a study of individuals, answers should be rounded up to the next whole number.
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 46 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).

From generation to generation, the mean age when smokers first start to smoke varies. However, the standard deviation of the age when smokers first start to smoke remains constant at around 2.1 years. The American Lung Association claims that the mean age when smokers first start to smoke is at least 17. A survey of 40 randomly selected smokers of this generation was done and it was found that the mean age when smokers first started to smoke was 18.1. Is there enough evidence to reject the claim? Describe what a Type I error is for this situation. Describe what a Type II error is for this situation.
= 222 mg/dLi and Total cholesterol levels for middle aged men (aged 55 – 64) follow approximately a normal distribution with mean, µ standard deviation, o = 37 mg/dLi. Those with a total cholesterol of 240 mg/dLi or higher have "high" cholesterol (and have twice the risk of coronary heart disease as someone with a total cholesterol less than 200 mg/dLi) Find the Z-score (standard score) for an observation of 290 mg/dl.
