Choose a randomly selected vehicle, and assume the annual mileage is normally distributed with a standard deviation of 1340 miles. Use Pthe Standard Normal Distribution Table. Round the final answer to at least four decimal places and intermediate \( z \)-value calculations to two decimal places. Part 1 of 3 (a) What is the probability that the vehicle was driven more than 15,000 miles? \[ P(X>15,000)=0.0307 \] Part 2 of 3 (b) What is the probability that the vehicle was driven less than 8000 miles? \[ P(X<8000)=0.0004 \] Part: 2 / 3 Part 3 of 3 (c) Would you buy a vehicle if you had been told that it had been driven less than 6000 miles in the past year? The probability of this being true for a randomly selected vehicle is \( \square \) , so I would want to get more information on why the number is so low, so that I can be sure that the odometer has not been tampered with.

Miles Driven Annually The mean number of miles driven per vehicle annually in the United States is 12,500 miles. Choose a randomly selected vehicle, and assume the annual mileage is normally distributed with a standard deviation of 1340 miles. Use Pthe Standard Normal Distribution Table. Round the final answer to at least four decimal places and intermediate \( z \)-value calculations to two decimal places.

Part 1 of 3
(a) What is the probability that the vehicle was driven more than 15,000 miles?
\[
P(X>15,000)=0.0307
\]

Part 2 of 3
(b) What is the probability that the vehicle was driven less than 8000 miles?
\[
P(X<8000)=0.0004
\]

Part: 2 / 3

Part 3 of 3
(c) Would you buy a vehicle if you had been told that it had been driven less than 6000 miles in the past year?

The probability of this being true for a randomly selected vehicle is \( \square \) , so I would want to get more information on why the number is so low, so that I can be sure that the odometer has not been tampered with.
