he policy of a particular bank branch is that its ATMs must be stocked with enough cash to satisfy customers making withdrawals over an entire weekend. At this branch, the average amount of money withdrawn from the ATM per customer transaction over the weekend is R240 with a standard deviation of R40. Suppose that the random sample of 36 customer transactions is examined and it is observed that the sample mean withdrawal is R258. Test at the 5% level of significance whether there is reason to believe that the true average withdrawal is greater than R240. Now define the hypothesis and provide the Critical Value and Region Then calculate the test statistic and provide a conclusion based on your data

Question
The policy of a particular bank branch is that its ATMs must be stocked with enough cash to satisfy customers making withdrawals over an entire weekend. At this branch, the average amount of money withdrawn from the ATM per customer transaction over the weekend is R240 with a standard deviation of R40. Suppose that the random sample of 36 customer transactions is examined and it is observed that the sample mean withdrawal is R258. Test at the 5% level of significance whether there is reason to believe that the true average withdrawal is greater than R240.
Now define the hypothesis and provide the Critical Value and Region
Then calculate the test statistic and provide a conclusion based on your data
