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? {Round your answer to 2 decimal place} mentmummmis _E {b} Suppose tire pressure is a normally distributed random variable with a standard deviation equal to 2 psi. If the car's average tire pressure is on target. what is the probability that the TPMS will trigger a warning? [Round your answer to 4 decimal places]
