Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 28% below the target pressure. Suppose the target tire pressure of a certain car is 30 psi (pounds per square inch.)
(a) At what psi will the TPMS trigger a warning for this car?
(b) Suppose the tire pressure is a normally distributed random variable with a standard deviation equal to 2psi. If the car's average tire pressure is on target, what is the probability that the TPMS will trigger a warning?
