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 H.

I am having a hard time with this question

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 u. Number of absences 0 1 2 3 4 5 6 7 8 9 10 Frequency 1 3 8 11 9 6 5 3 2 1 1 [Hint: The mean and variance of a Poisson variable both equal u, so X - Z = V H/n 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 - decimal places.) a) and solving the resulting inequalities for µ.] (Round your answers to two |× ) 3.52 4.64
