The lifetime of a certain type of automobile tire (in thousands of miles) is normally distributed with a mean of 37 and a standard deviation of 6. Find the following probabilities, round to the fourth. a) What is the probability 22 randomly chosen tires have an average lifetime greater than 40 Would it be unusual or usual for this to happen? b) What is the probability 22 randomly chosen tires have a lifetime less than 32
