4. An inspector wants to test if the Coke-litro-filling machine is defective by getting a random sample of 22 Coke litro from different batches filled by the machine. It is found out that the sample mean of the random sample is about 1.09 liters with a sample standard deviation of 0.15 liters. Which among the values is the critical regions applicable for the test? Use 0.01 level of significance. a. t > -2.831 and t < 2.831 b. t < -1.96 and t > 1.96 c. t < - 2.831 and t > 2.831 d. t > -1.96 and t < 1.96
