The sales price (in $1,000) of three-bedroom apartments in two citiesHouston, Texas, and Orlando, Floridaare given in the following table. Houston is known to have lower house prices than Orlando; however, it is not clear if it also has lesser variability in its prices.

Houston	189	145	220	205	225	275	248	310	150	318
Orlando	301	279	224	400	249	205	289	350	218	300

1. State the null and the alternative hypotheses to determine if the variance of house price in Houston is less than that in Orlando.
2. What assumption regarding the population is necessary to implement this step?

Test the hypothesis at = 0.05. What is your conclusion?
