The correct hypotheses to be tested are whether the mean amount of toothpaste filled by the machine is equal to 5.8 ounces or not. Therefore, the null hypothesis is that μ = 5.8 and the alternative hypothesis is that μ ≠ 5.8. Option B represents these hypotheses in the correct format. Option A incorrectly labels the null hypothesis as the alternative hypothesis. Option C incorrectly labels the alternative hypothesis as μ > 5.8, which represents overfilling. Option D incorrectly labels the null hypothesis as μ > 5.8, which represents overfilling.
