K (a) Determine the null and alternative hypotheses, (b) explain what it would mean to make a type I error, and (c) explain what it would mean to make a type II error. Three years ago, the mean price of a single-family home was $243,757. A real estate broker believes that the mean price has decreased since then. (a) Which of the following is the hypothesis test to be conducted? O A. Ho: μ = $243,757; H₁: >$243,757 B. Ho: u=$243,757; H₁: μ< $243,757 OC. Ho: μ = $243,757; H₁: μ# $243,757 (b) Which of the following is a type I error? OA. The broker rejects the hypothesis that the mean price is $243,757, when the true mean price is less than $243,757. B. The broker fails to reject the hypothesis that the mean price is $243,757, when the true mean price is less than $243,757. OC. The broker rejects the hypothesis that the mean price is $243,757, when it is the true mean cost. (c) Which of the following is a type II error? A.
