Quizplus · Accepted Answer

The null hypothesis should state that the mean number of tissues used during a cold is greater than or equal to 60, while the alternative hypothesis should state that the mean number of tissues used during a cold is less than 60. This is because we are testing whether there is evidence to support the claim that the mean number of tissues used during a cold is less than the reported mean of 60. Therefore, the correct null and alternative hypotheses are: H₀ : μ ≥ 60 and H₁: μ < 60.
