Problems 6 - 8: Suppose that the amount of coffee in each cup dispensed by a vending machine follows a normal distribution. A coffee vending machine is configured so that mean of all of the cups of coffee it dispenses is u = 12.0 ounces with a standard deviation o = 0.8 ounces. The mean of the distribution can be set by adjusting the filling machinery, while the standard deviation reflects the precision of the filling machinery. During a quality...

A coffee dispensing machine is supposed to deliver 8 ounces of liquid into each paper cup, but a consumer believes that the actual amount is less. As test he obtains a sample of 36 cups of the dispensed liquid and finds the mean content for his sample to be 7.5 ounces. If the machine operates with a standard deviation of 0.9 ounces, conduct a hypotheses test at a 0.05 level of significance as to the content of the coffee cup.

Question: An automatic coffee machine dispenses cups of coffee whose volume per cup varies normally and should have the mean μ = 10 oz if it is working correctly. A quality-control researcher randomly selects 8 cups of coffee from the machine and finds that in this sample the mean volume is 9.92 oz. and the standard deviation is 0.23 oz. In this problem, we have made slight changes to the "coffee machine" story above. In which of the options below...

A soft-drink machine is regulated to discharge an average of 7 ounce per cup. The amount of drink is considered normally distributed with a standard deviation of 0.5 ounce. What is the probability that a cup chosen at random will contain 7. C2 7,8 a) between 6.5,andR2 ounce? b) exactly 7.0 ounce? c) less than 7.3 ounce? d) If the cups hold exactly 8 ounces, what is the probability that a cup will overflow? e) What should be cup's size...

A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 6.9 ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain. Believing that the mean amount of coffee μ dispensed by the machine is less than 6.9 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed. BIG gathers a...

A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of eight ounces of coffee per cup. If it dispenses more that that on average, the corporation may lose money, and if it dispenses less, the customers may complain BIG Corporation would like to estimate the mean amount of coffee, H, dispensed per cup by this machine. BIG will choose a random sample of cup amounts dispensed by this machine and use this sample to estimate...

8. A company that manufactures and bottles apple juice uses a machine that automatically fills 16- ounce bottles. There is some variation, however, in the amounts of liquid dispensed into the bottles that are filled. The amount dispensed has been observed to be approximately normally distributed with mean 16 ounces and standard deviation 1 ounce (a) Determine the proportion of bottles that will have more than 17 ounces dispensed into them. (b) Suppose bottles are rejected if they have more...
