Extra Credit – 2 points Consider a queueing system with customers arriving according to a Poisson process at the rate of 5 per hour. Which of the following systems gives the lower steady-state expected time in system (i.e., waiting in line plus service time)? (A) Two “slow” parallel servers, each of whom can serve customers with Exp(3/hour) service times, or (B) One “fast” server, who can serve customers with Exp(6/hour) services?

Upload work to extra credit question (You will not receive extra credit without this; you will not receive extra credit for simply guessing correctly) I am looking specifically for 2 calculations (numbers) that would lead to the solution.  Create a distinct box at the top left with your key calculations.  Format: variable = xyz, average = 5.  Handwritten or highlighted in a box & color, just something to draw my eye to your solution and formulas.  Thanks!

In the “correlation network of ilities” graphic from the lecture, node size represents how often an ility appears in literature and edge thickness represents strength of relationship between two ilities. What does it mean if an ility appears near the center with a large node and many thick edges?

What are two (2) ways physical therapists can promote self-efficacy in the patients we work with?

You are tuning a Monte Carlo simulation to estimate the chance a serving of protein powder exceeds the lead limit.    

Customers arrive at Space Mountain in Disneyworld at the rate of 1000/hr according to a Poisson process. They form a long line and are served by one “server” at the rate of 1200/hr. Assume service times are exponential and first-come-first-served Find the steady-state expected waiting time   Units: seconds
