Suppose a food scientist wants to determine whether two experimental preservatives result in different mean shelf lives for bananas. He treats a simple random sample of 15 bananas with one of the preservatives. He then collects another simple random sample of 20 bananas and treats them with the other preservative. As the bananas age, the food scientist records the shelf life of all bananas in both samples. The food scientist does not know the population standard deviations. What test should the food scientist run in order to determine if the two experimental preservatives result in different mean shelf lives for bananas
