Find the mean of the data set: 4, 9, 18, 28, 32.
Note
Mean = sum of all values ÷ number of values. The sum is 91, and there are 5 values, so the mean is 91/5. The mean is the balancing value of the data set. Add all values carefully, then divide by how many values there are. The correct answer is 91/5, which matches the calculation or reasoning shown.
