Question:
With reference to Exercise 10.42, verify that the mean of the observed distribution is 1.6 , corresponding to \(40 \%\) of the cars requiring repairs. Then look up the probabilities for \(n=5\) and \(p=0.25\) in Table 1, calculate the expected frequencies, and test at the 0.05 level of significance whether the binomial distribution with \(n=5\) and \(p=0.25\) provides a suitable model for the situation.
