An online survey asked 1,004 adults "If purchasing a used car made certain upgrades or features more
affordable...."
The sample sizes of males and females were not provided. Supposed that both sample sizes were 502
and that 46 of the 502 males and 71 of the 502 females reported window tinting as their preferred
luxury upgrade of choice.
Is there evidence of a difference between males and females and the proportion who said they prefer
window tinting as a luxury upgrade at the 0.01 level of significance?
