A grоup оf scientists in а reseаrch lаb wоrk on experimental ants they receive from field-scientists in the California desert. 5 scientists are available to work on the experimental ants. Each scientist can work on an average of 20 ants per day according to an exponential distribution. The research lab receives experimental ants from field-scientists at an average of 45 ants per day with an exponential interarrival time. What is the expected time to work on an ant from arrival at the research lab until completion? BOX YOUR ANSWERS AND SHOW ALL YOUR WORK.
