Question

The transmission on a model of a specific car has a warranty of 40,000 miles. It is known that the life of such a transmission has a normal distribution with a mean of 72,000 and a standard deviation of 13,000 miles.

(Give your answer as a percentage correct to two decimal places. Do not put the % symbol in the answer box)

What % of transmissions will fail before the end of the warranty period?

What % of transmissions will be good for more than 100,000 miles?

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.
