Airline pilots face the risk of progressive hearing loss due to the noisy cockpits of most jet aircraft. Much of the noise comes from air roar which increases at high speeds rather than from the engines. The cockpit noise was measured to the left of the pilot's ear on 60 randomly selected flights of one type of aircraft. The computer output below shows the results from a regression model in which the noise level was predicted by the air speed. Assume the conditions of the linear regression model are satisfied.
Choose the correct null and alternative hypotheses to test whether there is a relationship between cockpit noise and air speed.
◦
H0: There is no relationship between cockpit noise and air speed.
Ha: There is a negative relationship between cockpit noise and air speed.
◦
H0: There is a relationship between cockpit noise and air speed.
Ha: There is no relationship between cockpit noise and air speed.
◦
H0: The correlation between cockpit noise and air speed is positive.
Ha: There is no correlation between cockpit noise and air speed.
◦
H0: There is no relationship between cockpit noise and air speed.
Ha: There is a relationship between cockpit noise and air speed.
