There is no sufficient evidence to support the owner's claim that he average attendance at games is over 523
Explanation:
From the question we are told that
The population mean is
![\mu = 523](https://img.qammunity.org/2021/formulas/mathematics/college/mxs8sxaubhdt0enkrc0i0vz3mrpyv29nnz.png)
Generally
The null hypothesis is
![H_o : \mu = 523](https://img.qammunity.org/2021/formulas/mathematics/college/r2kp4fwj3u0vurng5zhgeqq8e4dz5diaur.png)
The alternative hypothesis
( Original claim )
Given in the question that the conclusion is failure to reject the null hypothesis
Then we can conclude that there is no sufficient evidence to support the owner's claim that he average attendance at games is over 523
Note : In every hypothesis test the null hypothesis must contain a equality sign and any other inequality sign
