The Họ: X1 – 82 = 0, Ha: X1 – 82 > 0 hypothesis is that empty homes are not as appealing to buyers as staged homes and, therefore, sell for lower prices than staged homes. The mean selling price of the 5 empty homes was $150,000 with a standard deviation of $22,000. The mean selling price of the 5 staged homes was $175,000 with a standard deviation of 35,000.

01:22:15 A real-estate agent conducted an experiment to test the effect of selling a staged home vs. selling an empty Let µ = the true mean selling price of all empty homes and u, = the true mean selling price of all staged homes. What are the appropriate hypotheses? home. To do so, the agent obtained a list of 10 comparable homes just listed for sale that were currently empty. He randomly assigned 5 of the homes to be "staged," meaning they were filled with nice Ho: Hi - Hz =0, Hg: Hi - Hz < O Họ: H4 - H2 =0, Hai µ1 - Hz>0 furniture and decorated. The owners of the 5 homes all Họ: 81 – 82 = 0, Hgi 81- 82 < 0 agreed to have their homes staged by professional decorators. The other 5 homes remained empty. The Họ: X1 – 82 = 0, Ha: X1 – 82 > 0 hypothesis is that empty homes are not as appealing to buyers as staged homes and, therefore, sell for lower prices than staged homes.
