Question

the table shows the heights, in inches, of players on a girls basketball team.
basketball team heights
70 68 72 66 68
69 66 71 74 66
what is the mean height, rounded to the nearest whole number if necessary?
○ 66
○ 68
○ 69
○ 70

Explanation:

Step1: Sum all height values

$70 + 68 + 72 + 66 + 68 + 69 + 66 + 71 + 74 + 66 = 690$

Step2: Count total number of players

There are 10 players, so $n=10$

Step3: Calculate the mean

$\text{Mean} = \frac{\text{Total Sum}}{\text{Number of Players}} = \frac{690}{10} = 69$

Step4: Round to nearest whole number

69 is already a whole number, no rounding needed.

Answer:

69
