Unformatted text preview: In-class exercise #6 Probability density and cumulative probabilityfunctions for the exponential probability distributionsThis exercise is an application of chapter 6, equation 6.4 and figure 6.10, for the exponential function, obtaining both the density and the cumulative probability functions from Excel, and then using two vertical axes for the graphing.A. Assume there are only two possible rates of customer arrival: 1) once every 4 minutes, and 2) once every 10 minutes. As discussed in section 6.3, the rate of arrival (customers per unit of time) follows the Poisson distribution of chapter 5, and the time between arrivals follows the exponential distribution of chapter 6. B. On a worksheet create a column for possible times (minutes) until the next arrival of X0 = 0, .5, 1.0, 1.5, 2.0,….., up to 20.0 (i.e. steps of .5 minutes)....
