An Online Catalog Company Wants On-Time Delivery for at Least $\mathrm{H}_{0}: p>0.90$

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?

A) $\mathrm{H}_{0}: p>0.90$
$\mathrm{H}_{A}: p=0.90$

B) $\mathrm{H}_{0}: p<0.90$
$\mathrm{H}_{A}: p=0.90$

C) $\mathrm{H}_{0}: p=0.90$
$\mathrm{H}_{A}: p>0.90$

D) $\mathrm{H}_{0}: p=0.90$
$\mathrm{H}_{A}: p \times 0.90$

E) $\mathrm{H}_{0}: p=0.90$
$\mathrm{H}_{A}: p<0.90$
