$1$ It's Me$,$ Hi$,$ I$\text{'}$m the $($First$)$ Problem, It's Me Swifties arrive at SoFi Stadium at a rate of $\backslash$lambda $=13$ Swifties per minute, and they are processed through security at a rate of $\backslash$mu $=7$ Swifties per minute. Describe how I might figure out what the mean time between arrivals is$,$ then find it$.$ Describe how I might find the variance of the security processing time, then find it$.$ In queueing, the utilization of a processing station $($like the security here$)$ is given by $\backslash$rho $=(\backslash$lambda $)/(\backslash$mu $).$ Find the utilization, then describe what it means $($in the practical sense$)$ that the utilization is greater than $1.$ To get Taylor's attention, I$\text{'}$m thinking about running a regression analysis for her. Describe why using regression to predict the time spent waiting in line is a bad idea here. $($Assume that Taylor Swift loves properly conducted regression analyses.$)$
