(1 point) Among drivers who have had a car crash in the last year, 110 were randomly selected and categorized by age, with the results listed in the table below.
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%, 13% of the subjects respectively. At the 0.05 significance level, test the claim that the distribution of crashes conforms to the distribution of ages.

The test statistic is
The critical value is
The conclusion is
◯ A. There is sufficient evidence to warrant the rejection of the claim that the distribution of crashes conforms to the distribution of ages.
◯ B. There is not sufficient evidence to warrant the rejection of the claim that the distribution of crashes conforms to the distribution of ages.
