Answer

Answer:

The mean number of books to a box is 11.

Explanation:

Step1: Arrange data in ascending order

6, 6, 9, 9, 10, 11, 12, 14, 15, 18

Step2: Calculate the median

Since there are 10 data - points, the median is the average of the 5th and 6th ordered values. $\frac{10 + 11}{2}=10.5$.

Step3: Calculate the mean

The sum of the data is $6+6 + 9+9+10+11+12+14+15+18=110$. The mean is $\frac{110}{10}=11$.
