The sample proportion of adult gamers who tried the new Z-Box-Plus game and rated it "excellent," is:

The population proportion of gamers who rated the game as "excellent" is:

The test statistic is:
![z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{P(1-P)[\frac{1}{n_{1}}+\frac{1}{n_{2}} ]} } =\frac{0.80-0.72}{\sqrt{0.76(1-0.76)[\frac{1}{200}+\frac{1}{200} ]} }=1.873](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B%5Chat%20p_%7B1%7D-%5Chat%20p_%7B2%7D%7D%7B%5Csqrt%7BP%281-P%29%5B%5Cfrac%7B1%7D%7Bn_%7B1%7D%7D%2B%5Cfrac%7B1%7D%7Bn_%7B2%7D%7D%20%5D%7D%20%7D%20%3D%5Cfrac%7B0.80-0.72%7D%7B%5Csqrt%7B0.76%281-0.76%29%5B%5Cfrac%7B1%7D%7B200%7D%2B%5Cfrac%7B1%7D%7B200%7D%20%5D%7D%20%7D%3D1.873)
Thus, the value of the test statistic is 1.873.
