Consider a scenario where you have two samples. Sample 1 contains 30 observations, has the sample average value of 37 and the sample standard deviation of 2.5. Sample 2 contains 20 observations, has the sample average of 39 and the sample standard deviation of 2.0. Based on this information, please conduct a 90% significance test for the hypothesis that the population mean 2 exceeds the population mean 1 by exactly 3. Please keep in mind that we dont know the population standard deviations but can assume that they are equal.
