A random sample of 160 car purchases 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. Find the P-value to test the claim that all ages have purchase rates proportional to their driving rates. Use α = 0.05.
age | under 26 | 26-45 | 45-65 | over 60 |
purchases | 66 | 39 | 25 |
30 |
