Problem 11.6. Source: Sample STAM problem #179. The time to an accident follows an exponential distribution. A random sample of size two has a mean time of 4. Let Y denote the average of a new sample of size two from the same distribution. Calculate the maximum likelihood estimate of P[Y>8]. Hint: Remember that the sum of independent, identically distributed exponential random variables has a gamma distribution. You can convince yourselves of this fact using moment generating functions.
