The cerebral blood flow (CBF) in the brains of healthy
people is normally distributed with mean of 74 and a
standard deviation of 16. In a sample of 1000 people:
What is the proportion of healthy people will have CBF
readings below 100?
How many healthy people from the sample will have CBE
readings between 60 and 80?
Suppose the breathing rates of human adults per minute
is approximately normal with mean of 16 and standard
deviation Of 4. If a person is selected at random from a
sample of 500 persons.
What is the probability that the breathing rates of the
person selected exceed 22?
How many persons have breathing rates between 19 and
25?
Answer

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
