Chapter 7, Problem 26(choose chapter or problem)
The superintendent of a large school district, having oncehad a course in probability and statistics, believes that thenumber of teachers absent on any given day has a Poissondistribution with parameter m. Use the accompanying dataon absences for 50 days to obtain a large-sample CI for m.[Hint: The mean and variance of a Poisson variable bothequal m, soZ 5X 2 m1m/nhas approximately a standard normal distribution. Now proceedas in the derivation of the interval for p by making aprobability statement (with probability ) and solvingthe resulting inequalities for see the argument just after(7.10).]
