At a water bottling facility, a technician is testing a bottle filling machine that is supposed to deliver 1,000 milliliters of water. The technician dispenses 42 samples of water and determines the volume of each sample. The 42 samples have a mean volume of x = 1.001.1 mL . The machine is out of calibration if the mean volume differs from 1,000 mL. The technician wants to perform a hypothesis test to determine whether the machine is out of calibration. The standard deviation of the dispensed volume is known to be o = 6.1. Compute the value of the test statistic. 2.89 0.18 1.17 0.17
