An online catalog company wants on-time delivery for at least 90% of the orders they ship. They have been shipping orders via UPS and FedEx but will switch to a more expensive service (ShipFast) if there is evidence that this service can exceed the 90% on-time goal. As a test the company sends a random sample of orders via ShipFast, and then makes follow-up phone calls to see if these orders arrived on time. Which hypotheses should they test?

▸ H0: p = 0.90
HA: p > 0.90

▸ H0: p < 0.90
HA: p = 0.90

▸ H0: p > 0.90
HA: p = 0.90

▸ H0: p = 0.90
HA: p ≠ 0.90

▸ H0: p = 0.90
HA: p < 0.90
