A maker of high fiber cereal is looking for additional material to market its product. It already uses the "healthy image of high-fiber" but wants to exploit the issue even more. Its officers believe that people who eat high-ber cereal for breakfast consume, on average, fewer calories than people who do not eat high-fiber cereal for breakfast. To test their claim, the company interviewed 300 people, identified each person as a consumer or a nonconsumer of high- fiber cereal, and recorded the number of calories each person consumed at lunch. Can this high fiber producer claim that people eating high-fiber cereal for breakfast consume fewer calories for lunch? For this problem assume that you are dealing with two populations with unequal variances. What is the distribution of the test statistic? Use "Formula Sheet Fall 2020" if necessary. Select one: O a.
