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. What is the conclusion, and why?
