In a study of vehicle ownership, it has been found that 30% of U. S. households do not own a vehicle, with 50% owning 1 vehicle, and the remaining owning 2 or more vehicles. The data for a random sample of 191 households in a resort community are as follows: 53 owned 0 vehicles, 103 owned 1 vehicle, and the remaining owned 2 or more vehicles.

When testing (at the 5% level of significance) whether the vehicle-ownership distribution in this community differs from that of the nation as a whole what is the test statistic? (please round your answer to 3 decimal places)
