Answer: 11.667
Step-by-step explanation:
The formula to find the test statistic for chi-square test is given by :-
![\chi^2=\dfrac{(n-1)\cdot s^2}{\sigma^2}](https://tex.z-dn.net/?f=%5Cchi%5E2%3D%5Cdfrac%7B%28n-1%29%5Ccdot%20s%5E2%7D%7B%5Csigma%5E2%7D)
Given : Claim : ![\sigma^2=12.6](https://tex.z-dn.net/?f=%5Csigma%5E2%3D12.6)
![n = 15\ ;\ s^2 = 10.5](https://tex.z-dn.net/?f=n%20%3D%2015%5C%20%3B%5C%20s%5E2%20%3D%2010.5)
Then , the standardized test statistic will be :-
![\chi^2=\dfrac{(15-1)\cdot 10.5}{12.6}\\\\=\dfrac{14\cdot 10.5}{12.6}=11.6666666667\approx11.667](https://tex.z-dn.net/?f=%5Cchi%5E2%3D%5Cdfrac%7B%2815-1%29%5Ccdot%2010.5%7D%7B12.6%7D%5C%5C%5C%5C%3D%5Cdfrac%7B14%5Ccdot%2010.5%7D%7B12.6%7D%3D11.6666666667%5Capprox11.667)
Hence, the standardized test statistic ![\chi^2=11.667](https://tex.z-dn.net/?f=%5Cchi%5E2%3D11.667)
