Conduct the hypothesis test and provide the test statistic, critical value and/or P- value and state the conclusion.
Do World War II Bomb Hits Fit a Poisson Distribution? In analyzing hits by V-1 buzz bombs in World War II, South London was subdivided into regions, each with an area of 0.25 km2. Shown below is a table of actual frequencies of hits and the frequencies expected with the Poisson distribution. Use the values listed and a 0.05 significance level to test the claim that the actual frequencies fit a Poison distribution.
Number of bomb hits 0 1 2 3 4 or moreActual number of regions 229 211 93 35 8Expected number of regions 227.5 211.4 97.9 30.5 8.7(from Poisson distribution)
