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) $H _ { 0 } : p = 98.6 ^ { \circ } \mathrm { F }$
B) $H _ { 0 } : p

Question

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) $H _ { 0 } : p = 98.6 ^ { \circ } \mathrm { F }$
B) $H _ { 0 } : p < 98.6 ^ { \circ } \mathrm { F }$
C) $H _ { 0 } : \mu \neq 98.6 ^ { \circ } \mathrm { F }$
D) $H _ { 0 } : \mu = 98.6 ^ { \circ } \mathrm { F }$

Quizplus · Accepted Answer

The null hypothesis for a hypothesis test is the statement being tested or the assumption made about the population parameter. In this case, the claim is that the mean body temperature is equal to 98.6°F. Therefore, the null hypothesis is that the population mean body temperature is equal to 98.6°F, which is denoted by H0: μ = 98.6°F. Option D correctly represents the null hypothesis, while options A and B represent hypotheses for proportions, and option C represents an alternative hypothesis.
