The mean arrival rate of vehicles (Poisson process) is 1.08 (based on previous observations). Assume that the minimum arrival rate is 10% less than the estimated value 1.08), and that maximum arrival rate is 10% greater than the estimated value 1.08). Hence there are three arrival rate estimates (min, expected, and max). Assume that these three value are equally likely (0.333 probability each). Given that you next observe the following 6toll booth vehicle arrival data, per minute - 2,2,2,2,4,3. Draw a figure showing how your probabilities estimates of the three arrival rates (min, expected, and max) change with new data.

Their major customer is a large west-coast aircraft manufacturer.
Currently, Western has substantial unused capacity due to a
downturn in production for this major customer. This in turn has
caused a significant drop in profits at Western since their workers
are highly skilled and Western does not want to reduce head-count
during this downturn which they expect to be temporary. Sally...
