You are conducting a hypothesis test about how much beer is in a can. Your null hypothesis is that true fill quantity is less than or equal to 8 ounces. Your test will be at the 0.05 significance level. You take a sample of 64 cans (a large and tasty sample), and find that the sample average is 8.02 ounces, and the standard deviation is 0.50. What is/are the critical values for this test?   Group of answer choices -1.64 -1.64 and 1.64 1.96 1.64
