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 the heights

First, we list out all the heights: 70, 68, 72, 66, 68, 69, 66, 71, 74, 66.
Now we sum them up:

$$
LATEXBLOCK0
$$

Step2: Calculate the mean

There are 10 data points (since there are 10 heights in the table). The formula for the mean (\(\bar{x}\)) is \(\bar{x}=\frac{\sum x}{n}\), where \(\sum x\) is the sum of the data and \(n\) is the number of data points.
We know \(\sum x = 690\) and \(n = 10\), so the mean is \(\frac{690}{10}=69\).

Answer:

69
