A Local Eat-In Pizza Restaurant Wants to Investigate the Possibility $H _ { 0 } : \mu < 38$

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time
Spent on a delivery does not exceed 38 minutes. The owner has randomly selected 27 customers
And delivered pizzas to their homes. What hypotheses should the owner test to demonstrate that
The pizza delivery will not be successful?

A) $H _ { 0 } : \mu < 38$ vs. $H _ { \mathrm { a } } : \mu = 38$
B) $H _ { 0 } : \mu = 38$ vs. $H _ { \mathrm { a } } : \mu \neq 38$
C) $H _ { 0 } : \mu = 38$ vs. $H _ { \mathrm { a } } : \mu > 38$
D) $H _ { 0 } : \mu = 38$ vs. $H _ { \mathrm { a } } : \mu < 38$
