Atire company measures the tread on newly-produced tires and finds that they are normally distributed with a mean depth of 0.99mm and a standard deviation of 0.35mm. find the probability that a randomly selected tire will have a depth less than 0.31mm. would this outcome warrant a refund (meaning that it would be unusual)?
