When the Blackhawks completed their successful Stanley Cup run this summer, they decided to get much needed haircuts. The closest hair salon to the United Center is TQ Cuts, a small operation owned by Harry Mann. Harry is not just the owner, but the only stylist at TQ Cuts. During busy periods, three customers walk into TQ Cuts every hour (assume interarrival times are exponentially distributed). Hearing that the team would like to come in for haircuts, Harry realizes the amount of time required for these shaggy customers will be excessive, increasing his average service time to 25 minutes (with a standard deviation of 25 minutes) and considers hiring another stylist for his business. How long would a customer expect to wait in line now (rounded to the nearest minute), if Harry actually hired the stylist?
