• A)At α = 0.05,there is not sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
• B)At α = 0.05,there is sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
• C)At α = 0.05,there is insufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues.
