a plumbing supplier's mean monthly demand for vinyl washers is 24212 with a standard deviation of 6053. The mean monthly demand for stem boilers is 6.8 with a standard deviation of 1.7. Comapre the dispersion of these distributions. Which demand pattern has more relative variation? Explain

In this case, they are both the same.
(std. dev.)/mean = .250 for both
