1. Simulate 20 observations on the random variable X, the time to failure of the signal lights on an automobile. Approximate the average time to failure for these lights based on the simulated data. Does this value agree well with the theoretical mean value for X?
2. A satellite has malfunctioned and is expected to reenter the earths atmosphere sometime during a four-hour period. Let X denote the time of reentry. Assume that X is uniformly distriwed over the interval [0,41 Simulate 20 observations on X.
