Management at a video game store wants to gain a better understanding of their customers. In order to better manage advertising directed towards different customers, they want to determine if the average amount spent by men and women at the store is different. They take a random sample of 39 men and 69 women customer. They find that on average, men in their sample spent about $150.63 with a standard deviation of $49.63 when they shopped at the store. On average, women in the sample spent about $332.40 with a standard deviation of $32.04 when they shopped at the store. Using a two-sample t-test, calculate the test statistic (t- statistic) associated with this test (HA: µm – µw + 0) (Your value may be larger than what you are used to see for a test-statistic, that is OK).
