Assume that the systolic blood pressure of a 30 year old male is normally distributed with an average of 122 mmHg (millimeters of mercury) and a standard deviation of 10 mmHg. Calculate the probability that the average blood pressure of a randomly selected 30 year old male will be greater than 125 mmHg (nearest ten thousandth)

Assume that adults have IQ scores that are normally distributed with a mean of µ = 100 and a standard deviation o = 20. Find the probability that a randomly selected adult has an IQ between 80 and 120.

Females have pulse rates that are normally distributed with a mean of 74 beats per minute and a standard deviation of 12.5 beats per minute.  If 16 adult female are randomly selected, find the probability that their pulse rates are less than 70 beats per minute. Express your answer as a percent rounded to 2 decimal places.

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 69 with a standard deviation of 7.5. Assume that the distribution is approximately normal.Find the probability that an elite athlete has a maximum oxygen uptake of at least 88.5 ml/kg.   Find the probability that an elite athlete has a maximum oxygen uptake of at most 48.75 ml/kg.   Find the probability that an elite athlete has a maximum oxygen uptake of 48.75 ml/kg.
