Question

A publisher reports that 44 % of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually above the reported percentage. A random sample of 340 found that 50 % of the readers owned a particular make of car. Is there sufficient evidence at the 0.05 level to support the executive's claim?
