a = A production manager would like to conduct a hypothesis test ( 0.05) to determine whether the variance in diameters of ball bearings produced by two machines differs (Ho: 0} = 02). The data below show the diameters (in millimeters) of two independent samples of ball bearings produced by the two machines. According to the information, answer the following two questions. Machine A Machine B 1.96 2.25 2.01 2.03 2.22 1.93 1.93 1.89 1.99 2.03 1.98 1.84 2.37 2.45 1.83 2.29 2.1 1.65 1.97 2.45 2.32 2.16
What is the critical value? Keep 2 decimals.
