The null hypothesis states that the average number of tissues used during the course of a cold is equal to 40. The alternative hypothesis is that the average number of Puffs brand tissues needed is less than 40. This is because Puffs brand tissues believe that their tissues are more effective than other tissues, therefore fewer of their tissues would be needed. The alternative hypothesis reflects this belief as it compares the average to a lower value (less than 40).
