Question
Hypothesis Testing Practice Questions State and define the 7 steps in testing a hypothesis. 2. At the PRD Bank, it took an average of 40 minutes for a new clerk to learn to post cheques and vouchers to its real time system. Recently the PRD Bank changed its IT system. As the IT Manager, you want to find if the mean time taken by new clerks to learn to post cheques and vouchers on the new system is different from 40 minutes. A sample of 38 clerks showed that it took, on average, 37 minutes for them to learn to post cheques and vouchers on the new system, with a standard deviation of 7 minutes. 5-sigma ref- to the moter Find the p-value for the test that the mean learning time to post cheques and vouchers on the new system is different from 40 minutes. What will your conclusion be if alpha = .01. - Population standard deviation from an infinite number of measurer - sample standard deviation of a finite number of measur mean -Sampl population mean ample standard deviention
