The amount of coffee dispensed by a drink vending machine is normally distributed with a mean of 12.1 oz. What is the probability that a randomly selected cup of coffee has more than 12.8 oz? Assume that the standard deviation for all drink vending machines is 0.38
Solutions
Expert Solution
Let "X" be the amount of coffee dispensed by a drink vending machine.
Refer Standard normal table/Z-table to find the probability or use excel formula "=NORM.S.DIST(1.84, TRUE)" to find the probability.

A soft drink machine is regulated so that the amount of drink
dispensed is approximately normally distributed with a standard
deviation equal to 1.5 deciliters. Find the 95% confidence interval
for the mean of all soft drinks dispensed by this machine if a
random sample of 36 drinks had an average content of 22.5
deciliters. What statistical table to be used? What is the tabular
value? What is the computed lower confidence limit? What is the
computed upper confidence limit?
