You are conducting a hypothesis test about income where the research (alternative) hypothesis is that popoulation mean is less than $60,000. You take a sample of 100 people (a large sample), and find that the sample average is $65,000, and the standard error is 130. Your test will be at the 0.10 significance level. What is/are the critical values for this test? Group of answer choices 1.28 -1.64 -1.28 -1.28 and 1.28
