To calculate the sample mean height, you need to add all the heights together and then divide by the number of measurements.
The heights of the six girls are: 64, 67, 65, 71, 73, and 69.
1. First, sum the heights:
\( 64 + 67 + 65 + 71 + 73 + 69 = 409 \)
2. Next, divide the total by the number of girls (6):
\( \text{Mean} = \frac{409}{6} \approx 68.1667 \)
3. Finally, round to the nearest inch:
\( 68.1667 \) rounded to the nearest inch is \( 68 \).
Therefore, the sample mean height is **68 inches**.
