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. Test the claim that regular Coke and diet Coke have weights with different standard deviations. Sample weights are found in Data Set 17 in Ap- pendix B, but here are the summary statistics: The sample of 36 weights of regular Coke have a standard deviation of 0.007507 lb, and the sample of 36 weights of diet Coke have a standard deviation of 0.004391 lb. Use a 0.05 significance level. If the results were to show that the standard deviations are significantly different, what would be an important factor that might explain the difference?
