Step-by-step explanation:
Given that a random sample of 160 car crashes are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65.
<26 26-45 46-65` >65
Observed O 66 39 25 30 160
Expected E 40 40 40 40 160
Chi square
(O-E)^2/E 16.9 0.025 5.625 2.5 25.05
Thus we get chi square test statistic = 25.05
