Answer:

The new average is 9 years.

Step-by-step explanation:

The mean age of 5 students is 10 years.

The sum of their ages is:

\bar x=\frac{1}{5}\sum x\\10=\frac{1}{5}\sum x\\\sum x=50

A student of age 14 drops out.

The new sum of the ages of 4 students is,

\sum x=50-14=36

Compute the mean age of the 4 students as follows:

\bar x=\frac{1}{4}\sum x\\=\frac{1}{4}\times36\\=9

Thus, the new average is 9 years.
