Quizplus · Accepted Answer

The mean weight of a peanut is the sum of the products of the weights and their frequencies divided by the total number of peanuts. The total number of peanuts is 430. The mean weight is:(0.755 * 3 + 0.815 * 2 + 0.875 * 2 + 0.935 * 2 + 0.995 * 168 + 1.055 * 241 + 1.115 * 12) / 430 = 1.059 g
