A production line operation is tested for filling weight accuracy using the following hypotheses.
Hypothesis | Conclusion and Action |
H 0: = 16 | Filling okay, keep running |
H a: 16 | Filling off standard; stop and adjust machine |
The sample size is 39 and the population standard deviation is = 0.9. Use = .05. Do not round intermediate calculations.

Use the critical value approach to state your conclusion for each of the following sample results. Use a = .05. a. With I-52.5, what is the value of the test statistic (to 2 decimals)? Can it be concluded that the population mean is greater than 50? b....
A hypothesis test is used to prevent a machine from overfilling or under filling bottles of soda. On the basis of a sample, the hypothesis is rejected and the machine is shut down for inspection. A thorough examination reveals there is nothing wrong with the filling machine. From a statistical point of view: A Type II error was made A correct decision was made A Type I and Type II error was made A Type I error was made
2side Hypothesis Testing_03 (two independent sam machines are used for filling plastic battle with a new volume of 16.0 ounces. The fill volume can be assumed was with standard deviations d. 0.020 and 0.025 ounces. A member of the quality engineering staff that both machines fill to the same mean net volume, whether or not this volume is 16.0 ounces. random sample of 10 bottles is taken from the output of each machine: Machine 01 16.03 16.01 16.04 15.96 16.05...
A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.1 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 dispensed by the machine, , is different from 7.1 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed. Technicians gather a...
A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.2 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 dispensed by the machine, H, is less than 7.2 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed.
