The length of time y necessary to complete a key operation in the construction of houses has an exponential distribution with mean 13 hours. the formula c = 100 + 80y + 3y2 relates the cost c of completing this operation to the square of the time to completion. the mean of c was found to be found to be 2,154 hours and the variance of c was found to be 10,440,820. how many standard deviations above the mean is 3,000 hours?
