Apply thechi-square goodness of fit test to the accompanying data on airport service times to determine if an exponential distribution models the data. Use interior bins of width 100, let the first bin extend between negative infinity and100, and let the last bin extend between 600 and infinity. Note that for an exponentialdistribution, the number of degrees of freedom for the CHISQ.INV.RT function should be the number of bins minus 2.
