5. A postmix beverage machine is adjusted to release a certain amount of syrup into a chamber where it is mixed with carbonated water. A random sample of 25 beverages was found to have a mean syrup content of 1.05 fluid ounces and a standard deviation of 0.15 fluid ounces. Assume that the syrup content of a beverage is normally distributed. (a) Give a point estimate for the mean syrup content in a beverage. Give also the (estimated) error of the estimate. (b) Construct a 95% confidence interval for (c) The goal is to have about one ounce of syrup per beverage. Use a critical region to test Ho: p=1 against Hi : p / 1 at a significance level of a = 5%
