B. A sample of 142 households in a town was taken. 40 reported to own a vehicle that can hold more than 4 people, while the other 102 reported they own a vehicle that can hold 4 people or less. The households were also surveyed about whether they had children or not. Does owning a vehicle that can hold more than 4 people also mean that you have children in the household?
