suppose the average amount of vacation time for an american worker is given by a normal distribution with mean 24 days, and standard deviation of 6 days. john wants to know the probability that he will have a job that has between 15 and 33 days of vacation. to do so, he standardizes days of vacation so he can use the standard normal distribution to compute the probability. the standardized values are -1.5 and 1.5, respectively. the probability that an individual has less than 15 days of vacation 0.067, and the probability an individual has less than 33 days of vacation is 0.933. what is the probability that an individual has between 15 and 33 days of vacation? include 3 decimal places, i.e., 3 digits to the right of the decimal.
