Transcribed Image Text:10.36 A study examining bomb hits in South London during World War II is documented in
the following table from the book A Handbook of Small Data Sets (Hand et al., 1993, p. 232).
The bomb hits were recorded in the 576 grids in a map of a region in South London. The study
contended that certain areas were less likely to be hit with a bomb because of certain geographi-
cal features. If the bomb hits were purely random, a Poisson model would produce the number
of hits per grid.
Number of bomb hits 01 2 3 4567 Total
Number of grids
229 211 93 35 70 0 1 576
a. Does the distribution of bomb hits appear to be random across this region ot
South London?
b. State the null and research hypotheses for this study in terms of m, the probability
of i bomb hits in a grid.
