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. If the null hypothesis is true, the sampling distribution of p-hat can be modeled with a normal distribution. What is the Standard Error of this normal distribution? (Round to three places after the decimal.)

Question

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.

If the null hypothesis is true, the sampling distribution of p-hat can be modeled with a normal distribution. What is the Standard Error of this normal distribution? (Round to three places after the decimal.)
