Independent random samples of 35 and 30 soft drinks are drawn from two soft-drink machines. Sample average content and standard deviation were obtained for both samples. The sample data is presented in the following table: Machine 1 Machine 21 Sample size 35 30 Sample mean 12 oz 11.5 Sample stand. dev. 0.05 oz 0.04 oz Do the data present sufficient evidence to indicate that the mean for the machine 1 is different from the mean for the machine 2? Use a 0.05 level of significance. Independent random samples of 35 and 30 soft drinks are drawn from two soft-drink machines.
