Chapter 5.4, Problem 36E

(a)

To determine

To calculate: The probability that a wait time is at most $1$ hour if the wait time at an emergency room has the probability density function $f\left(t\right)=0.116e^{-0.116t}$.

(b)

To determine

To prove: In $2009$, half of all the emergency room patients waited up to $6$ hours using the probability function $f\left(t\right)=0.116e^{-0.116t}$ for $0\le t\le \infty$ where $t$ is in hours.
