It is given that $n=50$

$H_0:渭=\$85,000$

$H_1:渭>\$85,000$

Once null hypothesis ${\mathrm{H}}_0$is true, type one error is rejecting null hypothesis $H_0$

We have convincing proof that mean financial gain of these living close to restaurant is larger than $85000$once mean financial gain of these living close to restaurant is actually $85000$.

Double consequence is that opening restaurant in this area where financial gain of people is not enough and hence restaurant can depart of business.

One null hypothesis $H_0$is false, type $II$error fail to reject $H_0$

There is not enough convincing proof that mean financial gain of these living close to restaurant is larger than $85000$, once mean financial gain of these living close to restaurant is actually $85000$.

Double consequence is that not opening restaurant in this area where financial gain of people is large enough and hence it can miss profitable location.
