A real estate agent claims that the mean living area of all single-family homes in his county is at least 2400 square feet.

You want to test, at the 5% significance level whether the real estate agent's claim is true. A. Write down the Ho/Ha for this test. Also indicate the tail of the test. Show all work. B. What will be the distribution used for this test? C. Using a diagram, show the R/NR regions for this test. Label these regions carefully.
