The mean of the waiting times in an emergency room is 83 minutes with a standard deviation of 15.5 minutes for people who are admitted for additional treatment. The mean waiting time for patients who are discharged after receiving treatment is 77 minutes with a standard deviation of 8.2 minutes. Calculate the coefficient of variation. Round your answers to one decimal place. Additional Treatment Cvar % and Discharged Cvar %
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
