(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 Il 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. The broker fails to reject the hypothesis that the mean
price is $243,757, when the true mean price is less than
$243,757.
OB. The broker rejects the hypothesis that the mean price is
$243,757, when it is the true mean cost.
C. The broker fails to reject the hypothesis that the mean
