The heights of players of a girls' basketball team are shown. Find the average height of the team to the nearest tenth.

Step-by-Step Solution

Answer

The average height of the team is 67.5 inches.

Step 1. Write the formulae used.

Average/mean of a data is: 

$\text{Average}=\frac{\text{sum of all the numbers in data}}{\text{Total number of numbers in data}}$

Step 2. Write the given information.

The height of the players is given in inches as 72, 71, 69, 66, 62, 70, 64, 69, 67, 65, 65, and 70. This is the height of 12 players.

Step 3. Description of step.

To find the average height of the team use the given data and formula for average mentioned above as:

$$\begin{gathered} \text{Average}=\frac{72+71+69+66+62+70+64+69+67+65+65+70}{\text{12}} \\ =\frac{810}{12} \\ =67.5 \end{gathered}$$

Thus, the average height of the team is 67.5 inches.
