Question

A manufacturer wishes to test the claim that one of its pancake mixes has a mean weight that does not equal 16 ounces as advertised.

A) $\mathrm { H } _ { 0 } : \mu = 16$ ounces
$\mathrm { H } _ { \mathrm { a } } : \mu > 16$ ounces

B) $H _ { 0 } : \mu = 16$ ounces
$\mathrm { H } _ { \mathrm { a } } : \mu < 16$ ounces

C) $\mathrm { H } _ { 0 } : \mu = 16$ ounces
$\mathrm { H } _ { \mathrm { a } } : \mu \neq 16$ ounces

D) $\mathrm { H } _ { 0 } : \mu \neq 16$ ounces
$\mathrm { H } _ { \mathrm { a } } : \mu = 16$ ounces

Quizplus · Accepted Answer

The correct hypothesis test for checking if the mean weight is not equal to 16 ounces is to set the null hypothesis ($H_0$) as the mean weight being equal to 16 ounces ($\mu = 16$) and the alternative hypothesis ($H_a$) as the mean weight being not equal to 16 ounces ($\mu \neq 16$). This is a two-tailed test.
