A survey was conducted in the San Francisco Bay area in which each participating individual was classified according to the type of vehicle used most often and city of residence. A subset of the resulting data are given in the accompanying table. Do the data provide convincing evidence of an association between city of residence and vehicle type? Use a significance level of 0.05. You may assume that it is reasonable to regard the sample as a random sample of Bay area residents. (Round your answer to two decimal places.)
Vehicle Type | City | ||
Concord | Pleasant Hills | North San Francisco | |
Small | 68 | 83 | 221 |
Compact | 63 | 68 | 107 |
Midsize | 88 | 123 | 142 |
Large | 24 | 18 | 11 |
