Answer to Problem 60E

The proportion is 23.33

Explanation of Solution

Number of varieties = 30

Number of varieties that contain more than 9 grams of protein = 7

The proportion of varieties that contain more than 9 grams of protein can be calculated as:

  Proportion of varieties = Number of varietiesTotal varieties×100=730×100=23.33

The required proportion is 23.33
