In a random sample of 400 items 80 are found to be defective. The management wants to test the null hypothesis that the population defective rate is equal to 0.22. Test this hypothesis at the significance level of 0.01 (perform a two sided test) and perform a lower tail test and an upper tail test for the same problem

A set of data was collected involving the number of defective items found in a random sample of 46 cases of light bulbs produced during a morning shift at a plant. A manager wants to know if the mean number of defective bulbs per case is greater than 20 during the morning shift. She will make her decision using a test with a level of significance of 0.10. The following information was determined for the sample of 46 cases: n...

A machine, when working properly, produces only 2% defective items. Periodically a sample is taken and tested to make sure that the machine is working properly. Suppose a random sample of 121 items produced by this machine was tested and was found to have 5 defective items at α=0.05, what is the critical proportion to compare to the sample proportion when deciding on whether the proportion of the population must be > 0.02? Answer in 4 decimal places. Please show...
