Final answer:
To find the mean height of the basketball players, add all the heights together and divide by the number of players. The mean height for the given data is 68.25 inches, which rounds to 68 inches.
Step-by-step explanation:
The mean height of players on the girls’ basketball team is calculated by summing the heights and then dividing by the number of players. For the given heights of 66, 68, 69, and 70 inches, we first add them together to get a total: 66 + 68 + 69 + 70 = 273 inches. Then we divide this sum by the number of players, which is 4, to find the mean height. So the calculation would be 273 inches ÷ 4 = 68.25 inches. Rounding to the nearest whole number, the mean height is 68 inches.
