It is commonly accepted that senior citizens who eat fast food regularly should experience a greater increase in weight and waist circumference than those who do not eat fast food regularly. A study asks "Does eating fast food lead to a greater increase in weight and waist circumference of senior citizens who eat fast food regularly than those who do not eat during the following year?" The participants are 50 senior citizens. They were randomly divided into two groups of 25 each. People in one group ate fast food regularly while those in the other group ate healthy food. One year later, an increase in weight and waist circumference were diagnosed for 14 people in the group eating fast food, while an increase in weight and waist circumference was diagnosed for only 2 people in the other group. Create a two-way table for these data. Include totals across and down.
