Question

the table shows the heights, in inches, of players on a girls basketball team.

basketball team heights
73, 68, 72, 65, 68
69, 65, 71, 74, 68

what is the mean height, rounded to the nearest whole number if necessary?

options:
68
69
70

Explanation:

Step1: List all the heights

The heights are: 70, 68, 72, 65, 68, 69, 65, 71, 74, 68.

Step2: Calculate the sum of the heights

Sum = \(70 + 68 + 72 + 65 + 68 + 69 + 65 + 71 + 74 + 68\)
First, add the numbers:
\(70+68 = 138\); \(138+72 = 210\); \(210+65 = 275\); \(275+68 = 343\); \(343+69 = 412\); \(412+65 = 477\); \(477+71 = 548\); \(548+74 = 622\); \(622+68 = 690\)

Step3: Calculate the mean

There are 10 data points. Mean = \(\frac{690}{10}=69\)

Answer:

69
