Problem 12.6 (Optional: Strong Law of Large Number). Let $X_1, X_2, \dots$ be a iid random sequence with $E[X_i] = 0$, $E[X_i^2] = \sigma^2$, and $E[|X_i|^4] < \infty$. Consider the sample mean \begin{equation*} \overline{X}_n := \frac{1}{n} \sum_{i=1}^n X_i. \end{equation*} (i) Show that $\overline{X}_n \stackrel{a.s.}{\rightarrow} 0$. Hint: You may use the fact that $E[\overline{X}_n^4] = \frac{n\gamma + 3n(n-1)\sigma^4}{n^4}$.

Uber drivers are paid based upon the time and distance of a given trip and the Uber fare rate in operation at the time that they are with a passenger. The Uber fare rate is determined through a system known as "surge pricing" that charges a higher rate during times when many passengers are seeking service. Which of the following is the best strategy to follow as an Uber driver if you wish to maximize your total compensation per hour of driving? Use the supply and demand for Uber rides to support your answer. A. Uber fares (and thus driver pay) are higher during busy times such as after a concert or sporting event lets out. Therefore, it is better to locate near event venues and drive during busy times when fares are high. B. The higher Uber fares charged during busy times such as after a concert or sporting event lets out decrease rider demand. Therefore, it is better to avoid large event venues and drive when fares are lower. C. The high Uber fares during busy times increase the number of Uber drivers in the area making it more difficult for the drivers to find passengers. Therefore, it is better to avoid large event venues and drive elsewhere. Use the appropriate supply-demand analysis to support the team answer.
