Can someone help? I don't know why I'm getting it wrong, thank you!
![Among drivers who have had a car crash in the last year, 160 were randomly selected
and categorized by age, with the results listed in the table below.
Age Under 25 25-44 | 45-64 Over 64
Drivers

37
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 0.1 significance level, test the claim that the distribution of
crashes conforms to the distribution of ages.
