Question

A research scholar from UCLA reports that mice will live an average of 40 months when the diet is strictly restricted and then fortified with vitamins and minerals proteins. Suppose the age of such a rat is normally distributed with a standard deviation of 6.3 . month. Find the probability that a mouse will live a. More than 32 months b. Less than 28 months c. Between 37 and 49 months.

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.
