Since the Fall of 2012, Public Schools Have Had to Meet

question 25

Multiple Choice

Since the fall of 2012, public schools have had to meet new nutrition standards (which included offering more fruits and vegetables) for their lunches. In 2013, the USDA (United States Department of Agriculture) reviewed data from the 2005 School Nutrition and Dietary Assessment to investigate whether students in schools that were already following the new standards (school group A) ate more fruits and vegetables than students in schools that were not following the new standards (school group B) .
You will be presented with some of the overall findings of the review and will then be asked questions related to these conclusions.
-Finding #2: An unexpected finding was that if students came from economically poor homes or homes that did not have adequate food, they did not have greater fruit and vegetable consumption in school. What hypothesis were the researchers likely testing that produced this finding?

• A) Students who come from families with high incomes are more likely to eat greater amounts of fruits and vegetables than students from families with low incomes.
• B) Students who come from families with adequate access to fruits and vegetables are more likely to eat greater amounts of these foods than students from families with low access to fruits and vegetables.
• C) Students who have families with their own gardens will be less likely to eat greater amounts of fruits and vegetables.
• D) Students who lack a high family income or who have low access to fruits and vegetables are more likely to eat greater amounts of these foods than students from families with a moderate income or who have adequate access to fruits and vegetables.
