A diabetes educator is working with a group of 15 patients who have been newly diagnosed with type 2 diabetes. She administers a brief pretest, reviews carbohydrate counting with them, and then asks them to complete a posttest assessing their knowledge of the total grams of carbohydrate found in one serving of four sample items brought to the class. The results are shown in Table 2-9.

The diabetes educator would like you to present her results in a grouped frequency table showing the frequency and percentage of those who passed the posttest with >70% and those who didn’t for the report she has to make to her funding agency. Show your product.
