The superintendent of a large school district, having once had a course in probability and statistics, believes that the number of teachers absent on any given day has a Poisson distribution with parameter μ. Use the accompanying data on absences for 50 days to obtain a 95% large-sample CI for μ. Number of absences Frequency 0 1 2 3 4 5 6 7 8 9 10 24 7 11 8 7 6 1 2 1 1 [Hint: The mean and variance of a Poisson variable both equal μ, so z= has approximately a standard normal distribution. Now proceed as in the derivation of the interval for p by making a probability statement (with probability 1 - a) and solving the resulting inequalities for u.] (Round your answers to two decimal places.) 3.95 X5.14 × )
