Quizplus · Accepted Answer

The mean price is calculated by summing all prices and dividing by the number of prices: (32.99 + 24.95 + 26.95 + 28.95 + 18.95 + 28.99 + 30.95 + 22.95 + 24.95 + 26.95 + 29.95 + 28.95) / 12 = 304.53 / 12 = 25.3775. The closest choice to the mean is $14.04, which seems to be an error in the options provided.
