The scenario:

You have been hired by your regional real estate company to determine if your region's housing prices and housing square footage are significantly different from those of the national market. The regional sales director has three questions that they want to see addressed in the report:

1. Are housing prices in your regional market lower than the national market average?
2. Is the square footage for homes in your region different than the average square footage for homes in the national market?
3. For your region, what is the range of values for the 95% confidence interval of square footage for homes in your market?

The question that I have is how do I write the null and alternative hypotheses?

Note: For means, define a hypothesis that is less than the population parameter. Specify your significance level.

The first photo is the data I analyzed, and the second one is the national statistics that I compare the Mid Atlantic region to that I was provided.
