Question

The patient recovery time from a particular surgical procedure is normally distributed with a mean of 6.6 days and standard deviation of 1.4 days. Write your answers in percent form. Round your answers to the nearest tenth of a percent.

a) What is the probability of spending less than 8 days in recovery? %
b) What is the probability of spending more than 6 days in recovery? %
c) What is the probability of spending between 6 days and 8 days in recovery? %

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.
