The average number of miles (in thousands) that a car's tire will function before needing replacement is 73 and the standard deviation is 11. Suppose that 17 randomly selected tires are tested. Round all answers to 4 decimal places if necessary. a. What is the distribution of x? x ~ N( 73 11 b. What is the distribution of æ? x ~ N( 73 2.6679 V c. If a randomly selected individual tire is tested, find the probability that the number of miles (in thousands) before it will need replacement is between 71.8 and 75.3. d. For the 17 tires tested, find the probability that the average miles (in thousands) before need of replacement is between 71.8 and 75.3.
