A researcher claims that the average cost of producing an event is $80,000. A sample of 28 producers has a mean of $83,100 and a standard deviation of $500. Is there enough evidence to reject the researcher’s claim at α = 0.05? In the given problem what must be the correct way to state the null and alternative hypotheses and the claim?
