A formal hypothesis test is to be conducted using the claim that the mean body temperature is equal to $98.6 ^ { \circ } \mathrm { F }$. What is the null hypothesis and how is it denoted?
A) $H _ { 0 } : \mu = 98.6 ^ { \circ } \mathrm { F }$
B) $H _ { 0 } : \mu \neq 98.6 ^ { \circ } \mathrm { F }$
C) $H _ { 0 } : p = 98.6 ^ { \circ } \mathrm { F }$
D) $H _ { 0 } : p

The null hypothesis is a statement of no effect or no difference, and it is denoted as $H_0$. In this case, it claims that the mean body temperature is equal to $98.6 ^{\circ} \mathrm{F}$, so $H_0: \mu = 98.6 ^{\circ} \mathrm{F}$.
