A machine dispenses a liquid drug into bottles in such a way that the standard deviation of te
contents is 81 milliliters. A new machine is tested on a sample of 24 containers and the
standard deviation for this sample group is found to be 26 milliliters. At the 0.05 level of
significance, test the claim that the amounts dispensed by the new machine have a smaller
standard deviation.
Select the correct test statistic and conclusion based on the null hypothesis.
Test statistic: x2 = 2.370. Fail to reject the null hypothesis.
Test statistic: x2 = 8.367. Reject the null hypothesis.
Test statistic: x2 = 2.370. Reject the null hypothesis.
Test statistic: x2 = 3.581. Fail to reject the null hypothesis.
