Question

A machine is designed to fill toothpaste tubes with 5.8 ounces of toothpaste. The manufacturer does not want any underfilling or overfilling. The correct hypotheses to be tested are
A) H0: μ ≠ 5.8 Ha: μ = 5.8
B) H0: μ = 5.8 Ha: μ ≠ 5.8
C) H0: μ > 5.8 Ha: μ ≤ 5.8
D) H0: μ ≥ 5.8 Ha: μ < 5.8

Quizplus · Accepted Answer

The correct hypotheses for this scenario would be H0: μ = 5.8 and Ha: μ ≠ 5.8. We want to test if the mean amount of toothpaste being filled in the tubes is equal to 5.8 ounces or not. Therefore, option B is the correct choice.
