Quizplus · Accepted Answer

To find the percentage of pizza products that contain between 10 and 25 grams of fat, we need to find the difference between the cumulative frequencies at the upper boundaries for 25 and 10 grams and divide that by the total sample size, which is 36.

Cumulative frequency at 25 grams = 33 
Cumulative frequency at 10 grams = 9

Percentage of pizza products with fat between 10 and 25 grams = (33-9)/36 x 100% = 81%

Therefore, the answer is B: 81%.
