A) $H _ { 0 } : \mu \neq 3 , H _ { 1 } : \mu 3$ B) $H _ { 0 } : \mu = 3 , H _ { 1 } : \mu \neq 3$ C) $H _ { 0 } : \mu \neq 3 , H _ { 1 } : \mu = 3$ D) $H _ { 0 } : \mu = 3 , H _ { 1 } : \mu

Question

A professor of math refutes the claim that the average student spends 3 hours studying for the midterm exam.Which hypothesis is used to test the claim?
A) $H _ { 0 } : \mu \neq 3 , H _ { 1 } : \mu > 3$
B) $H _ { 0 } : \mu = 3 , H _ { 1 } : \mu \neq 3$
C) $H _ { 0 } : \mu \neq 3 , H _ { 1 } : \mu = 3$
D) $H _ { 0 } : \mu = 3 , H _ { 1 } : \mu < 3$

Quizplus · Accepted Answer

The claim being refuted is that the average studying time is equal to 3 hours (i.e. $ H_0 : \mu = 3 $). The alternative hypothesis would be that the average studying time is not equal to 3 hours (i.e. $ H_1 : \mu 
eq 3 $). Therefore, the correct choice is B.
