A pharmaceutical company wants to answer the question whether it takes longer than 45 seconds for a drug in pill form to dissolve in the gastric juices of the stomach.A sample was taken from patients taken the given drug in pill form and times for the pills to be dissolved were measured.State the hypotheses to test this question.

A) $H _ { 0 } : \mu = 45 \mathrm { sec } ; H _ { A } : \mu \leq 45 \mathrm { sec }$
B) $H _ { 0 } : \mu < 45 \mathrm { sec } ; H _ { A } : \mu = 45 \mathrm { sec }$
C) $H _ { 0 } : \mu = 45 \mathrm { sec } ; H _ { A } : \mu > 45 \mathrm { sec }$
D) $H _ { 0 } : \mu \geq 45 \mathrm { sec } ; H _ { A } : \mu < 45 \mathrm { sec }$
E) $H _ { 0 } : \mu > 45 \mathrm { sec } ; H _ { A } : \mu \leq 45 \mathrm { sec }$
