A survey asks a random sample of 500 adults in ohio if they support an increase in the states sales tax from 5% to 6%, with the additional revenue going to education. Let p(hat) denote the proportion in the sample who say they support the increase. Suppose that 53% of all adults in ohio support the increase.
