A real estate agency says that the mean home sales price in City A is the same as in City B. The mean home sales price for 30 homes in City A is $127,474. Assume the population standard deviation is $25,876. The mean home sales price for 30 homes in City B is $112,258. Assume the population standard deviation is $27,113. At a = 0.01, is there enough evidence to reject the agency's claim? Complete parts (a) through
(d) below.
(a) Identify the claim and state H, and Ha.
What is the claim?
O A. The mean home sales price in City A is the same as in City B.
O B. The mean home sales price in City A is greater than as in City B.
O C. The mean home sales price in City A is less than in City B.
O D. The mean home sales price in City A is not the same as in City B.
Let City A be sample 1 and let City B be sample 2. Identify Ho and Ha.
Họ: H1
Ha: H1
(b) Find the critical value(s) and identify the rejection region. Select the correct choice below and fill in the answer box within your choice.
(Round to two decimal places as needed.)
