a car is designed to last an average of 12 years with a standard deviation of 0.8 years. what is the probability that a car will last less than 10 years?
The probability that the car will last less than 10 years would be .0062. With the given data (M = 12, SD = .8), i computed the z-score and looked it up on the z table. The answer yields .0062 or 0.62%. Thus, the probability is very little.
