Sagot :

The correct hypothesis relation is  is H₀ : μ ≥ 2,412. and Ha : μ < 2,412

According to the United States Census Bureau, the average area = 2, 412 square feet

Then the null hypothesis is

H₀ :μ ( mean ) area is greater than or equal to 2,412

H₀ : μ ≥ 2,412.

But, according to Jane, in her area, still families want a small home comparison to average.

Alternative hypothesis is that, mean area is less than 2,412 .
