Question #1: please provide detailed calculations

You work for a logistics company and your manager has asked you to evaluate their shipping and outbound svstem queue. Specicallv. the manager wants to better understand the relationship between packing rates and the resulting average amount of time a package spends in the system. The warehouse's average service rate is a function of the number of servers working such that (number_of_workers*72 = average jackages_serviced _per_hour). At any given time, the manager can have 16 to 24 workers in the warehouse. Assuming the warehouse operation meets Mlth model assumptions and has an average package arrival rate of 1000 packages/hour, what is the minimum number of workers required to meet the threshold of 12 seconds for the average time a package spends in the system? select the nearest whote number. C) 16 workers 0 18 workers 0 20 workers 0 24 workers Using the same model assumptions as the previous question and assuming your answer for the previous question being 21 sewers, what is the probability that exactly 7 packages are in the system? Round your answer to the nearest hundredth of a percent. 0 1.87% O 4.12% O 10.42% 0 12.36%
