Question

The pulse rate of 550 adult men approach a normal distribution with a mean of 80 bpm and a standard deviation of 7 bpm. (a) draw a normal curve distribution showing the z-scores and the raw scores. (b) what percent of the adults have a pulse rate of less than 70 bpm? (c) what percent of the adult have a pulse rate of more than 102 bpm? (d)how many adults have pulse rate between the normal 60 bpm to 100 bpm?

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.
