The average income in a certain area is assumed to be approximately $35,000. Assume the standard deviation of the incomes in the area to be $8,000. We wish to test if the average income in the area is less than $35,000. A SRS of size 36 yields a sample mean of $37,000. State the appropriate set of hypotheses to test whether the average income of this area is as assumed. Group of answer choices μ = $8,000 vs Ha: μ < $8,000 Ho: μ = $37,000 vs Ha: μ > $37,000 Ho: μ = $35,000 vs Ha: μ < $35,000 Ho: μ = $35,000 vs Ha: μ ≠ $35,000
