An automatic filling machine is used to fill bottles with liquid detergent. A random sample of 20 bottles results in a sample variance of fill volume of s^2 = 0.0153 (fluid oz)^2 . Assume that the fill volume is approximately normal. Compute a 95% upper confidence bound for the population standard deviation. Provide practical interpretation of the result.

An automatic filling machine is used to fill bottles with liquid detergent. A random sample of 20 bottles results in a sample variance of fill volume of s2 = 0.01532 (fluid ounce). If the variance of fill volume is too large, an unacceptable proportion of bottles will be under- or overfilled. We will assume that the fill volume is approximately normally distributed. Determine the 95% upper confidence bound of the variance.

A machine used for filling plastic bottles with a soft drink has a target mean fill volume of 2.9 liters and a known standard deviation of 0.05 liter. State the sampling distribution of the sample mean, if you obtain a random sample of 25 bottles. Options- X bar ~ N(2.9, 0.01) X ~ N(2.9, 0.01) X ~ N(2.9, 0.05)

A machine is used to fill Apple Juice bottles with juice. The machine has a known standard deviation of ? = 0.05 liters. The target mean fill volume is ? = 2.0 liters. A quality control manager obtains a random sample of 50 bottles. He will shut down the machine if the sample of these 50 bottles is less than 1.95 or greater than 2.1. What is the probability that the quality control manager will shut down the machine.?

(Operations Management) The following data (in milliliters) are the amount of liquid in the detergent bottles on an automated filling machine. Develop sample mean and sample range control charts using the first 10 samples. Is the process in control? Use the control charts developed in part a to decide if the 11th sample (also given below) indicates an out-of-control situation.
