**Swifities Queue and Security Processing at SoFi Stadium** Swifties (for the uncultured—that's what we call Taylor Swift fans) arrive at SoFi Stadium at a rate of λ₁ = 13 Swifties per minute, and they are processed through security at a rate of λ₂ = 7 Swifties per minute. - **Determining Mean Time Between Arrivals:** Describe how to figure out the mean time between arrivals, then find it. (Yes, you’ll need to pick a distribution here, and there is a right choice.) - **Finding Variance of Security Processing Time:** Describe how to find the variance of the security processing time, then find it. - **Queuing Theory Utilization:** In queuing theory (yes, that’s a real field of study), the utilization of a processing station (like the security here) is given by ρ = λ₁/λ₂ = 13/7. Describe what it means, in the practical sense, that the utilization is greater than 1. - **Regression Analysis Consideration:** To get Taylor’s attention, I’m thinking about running a regression analysis for her. Describe why using the “typical” linear regression and normal distribution theory to predict the time spent waiting in line is probably a bad idea here, even if I have a good set of predictor variables.
