Putting It Together: The V-2 Rocket in London In Thomas Pynchon’s book Gravity Rainbow, the characters discuss whether the Poisson probabilistic model can be used to describe the locations that Germany’s feared V-2 rocket would land in. They divided London into 0.25-km² regions. They then counted the number of rockets that landed in each region, with the following results:

(d) A total of  rockets was fired. Determine the expected number of rocket hits by computing “expected number of rockets” , where  is the probability of observing that particular number of hits in the region.

(e) Conduct a goodness-of-fit test for the distribution using the  level of significance. Do the rocket hits appear to be modeled by a Poisson random variable?
