Transcribed Image Text:The median price of homes in in a certain city was $228,830. A sample of 200 homes sold in a suburb of the city found 113 homes with sales prices over $228,830 and 87 homes with sales prices under $228,830. Can you conclude that the median price of homes in the suburb differs from the median price of homes in the entir
city? Use a = 0.05.
State the null and alternative hypotheses.
O Ho: Median # 228,830
H₂: Median = 228,830
O Ho: Median 2 228,830
H₂: Median < 228,830
Ho: Median = 228,830
H₂: Median # 228,830
O Ho: Median ≤ 228,830
H₂: Median > 228,830
O Ho: Median > 228,830
H₂: Median = 228,830
