A device that monitors the levels of pollutants has sensors that detect the amount of CO in the air. Placed in a particular location, it is known that the amount of CO is normally distributed with a mean of 6.23 ppm and a variance of 4.26 ppm 2 . (a) What is the probability that the CO level exceeds 9 ppm?(b) What is the probability that the CO level is between 5.5 ppm and 8.5 ppm? c. An alarm is to be activated if the CO levels exceed a certain threshold. Specify the threshold such that it is 3.25 standard deviations above the mean.
