20. The average monthly rent for one-bedroom apartments in Chattanooga has been $700. Because of the downturn in the real estate market, it is believed that there has been a decrease in the average rental. The correct hypotheses to be tested are
(A) \(H_0: \mu \geq 700\) v.s. \(H_a: \mu < 700\)
(B) \(H_0: \mu = 700\) v.s. \(H_a: \mu \neq 700\)
(C) \(H_0: \mu > 700\) v.s. \(H_a: \mu \leq 700\)
(D) \(H_0: \mu < 700\) v.s. \(H_a: \mu \geq 700\)
(E) \(H_0: \mu < 700\) v.s. \(H_a: \mu > 700\)
