Scenario: As a health educator, you have work with public school systems to increase children's awareness of nutrition. You believe that children that are educated on health foods will be more likely to choose to eat healthier snacks. Past research indicates that on average children eat 3.5 servings a day with a standard deviation of 1.0. After implementing a 6 week nutrition program in Valley Elementary School to N=25, the health educator finds that children are eating an average of 4.0 servings of fruit and vegetables a day. The health educator wants to be 95% confident that her program has been effective in increasing the amount of fruits and vegetables of children - can you help her?
