Answer
Explanation:
Step1: Arrange data in ascending order
$6,6,9,9,10,11,12,14,15,18$
Step2: Calculate the median
Since $n = 10$ (even), median=$\frac{\text{5th value}+\text{6th value}}{2}=\frac{10 + 11}{2}=10.5$
Step3: Calculate the mean
Mean=$\frac{6+6 + 9+9+10+11+12+14+15+18}{10}=\frac{110}{10}=11$
Answer:
The mean number of books to a box is 11.
