An airline claims that luggage is rarely lost (does not arrive at the destination at the same time as the passenger). The airline claims that if luggage is lost, in 87% of cases the airline is able to recover and deliver the luggage within 24 hours. A consumer watchdog group found a random sample of 125 people whose luggage was lost and found that 99 of them had their luggage recovered and returned within 24 hours. The Sample proportion p-hat is 99/125 = 0.792. The watchdog group wants to perform a hypothesis test against the claim that the airline is able to recover 87% of lost luggage in 24 hours. What is the test statistic?
