You are interested in carrying out a statistical test of income in a particular neighborhood. Your research (alternative) hypothesis is that overall neighborhood income is less than $30,000. You take a sample of 64 people, and find that the average income for your sample is only $27,500, while the standard deviation is $10,000. Your test will be at the 0.01 significance level. What is/are the critical values for this test? Group of answer choices -1.96 -2.33 and 2.33 -2.33 2.33
