$\sqrt{14} \cdot 11$ , $13$ , $5$ , $15$ , $14$

Step 1

Move $11$ to the left of $\sqrt{14}$ .

$11 \sqrt{14}, 13, 5, 15, 14$

Step 2

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{11 \sqrt{14} + 13 + 5 + 15 + 14}{5}$

Step 3.2

Add $18$ and $15$ .

$\frac{11 \sqrt{14} + 33 + 14}{5}$

Step 3.3

Add $33$ and $14$ .

$\frac{11 \sqrt{14} + 47}{5}$

Step 4

Divide.

$17.63164625$

Step 5

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.
