7. Interpreting Display from Weights of Regular Coke and Diet Coke This section included an example about a hypothesis test of the claim that weights of regular Coke and regular Pepsi have the same standard deviation. Use a 0.05 significance level to test the claim that regular Coke and diet Coke have weights with different standard deviations. Sample weights are found in Data Set 12 in Appendix B, but see the accompanying displayed results of the F test from the TI-83 84 Plus calculator. If the results were to show that the standard deviations are significantly different, what would be an important factor that might explain the difference?
