Problem 2: A developmental psychologist is interested in whether young children show a difference in their willingness to eat vegetables depending on the language used to describe them. She divides 20 3-year-old children into two groups. The children in one group are offered 80 grams of lima beans and told that the beans are healthy. The children in the other group are offered 80 grams of lima beans and told that the beans are tasty. She then measures the amount of lima beans eaten in grams by subtracting the weight of the beans (or lack thereof) after eating from 80 grams. Is there a significant difference in the amount of lima beans children eat depending on what they are told about them? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below (which continues on the next page).
