Test Content 3.5 Points Question 1 A bank has two branches, one of them is operator by one teller, the other is operated by a self service intelligent system.Customers arrive to each branch at a rate of 6 customers/hour (interarrival times exponentially distributed). The human operator (system 1 need serves 10 customers/hr (exponentially distributed). The other automated branch (system 2) 11 customers/hr (variability between customers is very low, the process can be modelled as constant) Select only the correct statements from the following: The probability of have 2 or less customers waiting in system 1 is about 0.5 B The average total time in the system for system 2 is equal to 5.75 minutes The probability of system 1 being empty is 0.4 The traffic intensity for both systems is less than 0.65 The average number of customers waiting in the line of system 1 is equall to system 2 F) The average number of customers waiting in the line of system 2 is lesser than system 1 19 minutes remaining Last veg here to search I C * Question 2 in Linear regression, the farther the forecast is from the current values the higher is the error.
