The average American eats 1.5 cups of vegetables a day (may not be accurate). A researcher is interested in whether teenagers eat less vegetables on average than does the average American. She takes a sample of 25 teenagers and asks how much vegetables they eat. She finds that the mean amount of vegetables her subjects eat a day is 1.1 cups with a standard deviation of 0.5. What would be the appropriate test for the researcher to use to test whether teenagers actually do eat less vegetables than the average American at an alpha level of .01
