Amachine is used to fill containers with a liquid product. fill volume can be assumed to be normally distributed. a random sample of ten containers is selected, and the net contents (oz) are as follows: 12.03, 12.01, 12.04, 12.02, 12.05, 11.98, 11.96, 12.02, 12.05, and 11.99.
(a) suppose that the manufacturer wants to be sure that the mean net contents exceeds 12 oz. what conclusions can be drawn from the data (use α= 0.01).
(b) construct a 95% two-sided confidence interval on the mean fill volume.
