Is there a difference in the weights of contents in a can of Diet Coke versus a regular can of Coke? In a random sample of n=36 cans of Diet Coke, the mean weight of the contents of a can was 0.78479 lbs with a standard deviation of 0.00439 lbs. In an independent random sample of n=36 cans of regular Coke, the mean weight of the contents of a can was 0.81682 lbs with a standard deviation of 0.00751 lbs. Assuming that both populations are normally distributed and that sigma1 to the power of 2 = sigma2 to the power of 2, determine whether there is a difference in the mean weight of the contents of a can of Diet Coke vs. regular Coke with a 5% significance level.
