,According to a company, about 3.4% of the items are wrong priced when scanned at a retail checkout
counter. A researcher randomly selected and purchased 600 items, and he found that 15 of the 600 were
incorrectly priced by the checkout scanner. The probability that more than 2.5% of the items would be
incorrectly priced when they are scanned is
