O 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 x = 1.10 fluid ounces and a standard deviation of s = 0.015 fluid ounces. Find a 95% Confidence Interval on the mean volume of syrup dispensed. 2 Let X1, . . ., Xn be n random samples of a normal distribution X ~ N(u, 300) where u is unknown. What sample size n is required such that the width of the 97 percent confidence interval is barely larger than 5
