Explanation

The correct answer is $10$ . The mean of a data set is calculated by dividing the sum of the data values by the number of data values in the data set. For this data set, the mean can be calculated as $\frac{6 + 8 + 16 + 4 + 17 + 26 + 8 + 5 + 5 + 5}{10}$ , which is equivalent to $StartFraction 100 Over 10 EndFraction$ , or $10$ .
