(b) The broker rejects the hypothesis that the mean price is $243,772, when it is the true mean cost.

(c) The <em>type II error</em> says that accept the when it is false.
Thus, <em>type II error</em> is: The broker fails to reject the null hypothesis that the mean price of single-single home is $243,772, when the true mean price is less than $243,772.
