Two machines are used for filling plastic bottles to a net volume of 16.0 ounces. A member of the quality engineering staff suspects that the machines are not filling to the same net volume. An experiment was conducted to obtain random samples (n=10) from each machine. The data are shown below.
1. Analyze this data to determine if the quality engineer is correct. Begin by performing an appropriate test to determine if the variances can be assumed equal (verify necessary assumptions and provide evidence). Use 5% significance for all tests.
