5. Car Crashes and Age Brackets Among drivers who have had a car
crash in the last year, 88 are randomly selected and categorized by
age, with the results listed in the accompanying table (based on
data from the Insurance Information Institute). If all ages have
the same crash rate, we would expect (because of the age
distribution of licensed drivers) the given categories to have 16%,
44%, 27%, and 13% of the subjects, respectively. At the 0.05
significance level,...
