I'm not sure which Template i'm supposed to use can you also explain which one and why?

You were hired by a local animal shelter to help improve operations. When cats are brought into the shelter, they must be seen by a veterinarian for a check-up. On average, two cats per hour arrive at the shelter (assume this follows a poisson distribution). It takes a vet an average of 30 minutes to complete a cat check-up (assume exponential service time). The shelter currently has three veterinarians who just work on the cat check-up. The shelter would like to reduce costs, if possible, by assigning some of these veterinarians to deal with other animals. However, they only have space to hold up to 5 cats who are waiting for the check-up, so they aren't sure if they can reduce the number of vets. A. What is the arrival rate per hour? B. What is the service rate per hour? (Enter an integer, i.e. "1") QUESTION 32 Refer to the information in Question 31 and the associated Excel template. (Report all values to four decimal places, i.e. "0.0012" or as a percentage with no decimal places, i.e. "50%") C. What is the expected number of cats waiting to see a vet? D. What is the expected time (in hours) that a cat spends waiting to see a vet and undergoing the check-up? E. What is the probability that there is one cat either waiting or undergoing a check-up? E. What is the minimum number of veterinarians that are needed for the cat check-up process? G. If the number of veterinarians is reduced to two, what is the average utilization of each vet? H. If the number of veterinarians is reduced to two, what is the probability that there is more than 5 cats waiting for the check-up?
