Answer:
Step-by-step explanation:
From the given information:
The mean ![\hat x = \dfrac{\sum x}{n}](https://tex.z-dn.net/?f=%5Chat%20x%20%3D%20%5Cdfrac%7B%5Csum%20x%7D%7Bn%7D)
![\hat x = \dfrac{25+36+41+28+29+32+29+37+34+34+37+35+30+36+31+31}{16}](https://tex.z-dn.net/?f=%5Chat%20x%20%3D%20%5Cdfrac%7B25%2B36%2B41%2B28%2B29%2B32%2B29%2B37%2B34%2B34%2B37%2B35%2B30%2B36%2B31%2B31%7D%7B16%7D)
![\overline{x} = \dfrac{535}{16}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%3D%20%5Cdfrac%7B535%7D%7B16%7D)
![\overline{x} = 33.44](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%3D%2033.44)
The sample variance is as follows:
![S^2 = \dfrac{\sum dx^2 - ( \dfrac{\sum dx)^2}{n} )}{n-1}](https://tex.z-dn.net/?f=S%5E2%20%3D%20%5Cdfrac%7B%5Csum%20dx%5E2%20-%20%28%20%5Cdfrac%7B%5Csum%20dx%29%5E2%7D%7Bn%7D%20%29%7D%7Bn-1%7D)
![S^2 = \dfrac{279- ( \dfrac{7}{15} )^2}{15}](https://tex.z-dn.net/?f=S%5E2%20%3D%20%5Cdfrac%7B279-%20%28%20%5Cdfrac%7B7%7D%7B15%7D%20%29%5E2%7D%7B15%7D)
![S^2 = 18.585](https://tex.z-dn.net/?f=S%5E2%20%3D%2018.585)
The answer is 9 because there are 3 possibilities for each kid.
