Assessment – Hypothesis Testing DIRECTION: For each of the given problems, conduct a hypothesis test (assume that the underlying population is normally distributed). 1. ATMS must be stocked with enough cash to satisfy customers making withdrawals over an entire weekend. But if too much cash is unnecessarily kept in the ATMS, the bank is forgoing the opportunity of investing the money and earning interest. Suppose that at a particular branch, the population mean amount of money withdrawn from ATMS per customer transaction over the weekend is Php8,000, with a population standard deviation of Php1,500. a. If a random sample of 36 customer transactions indicates that the sample mean withdrawal amount is Php8,600, is there evidence to believe that the population mean withdrawal amount is no longer Php8,000? (Use a 0.05 level of significance.)
