From a random sample of 17 students in an introductory finance class that uses group-learning techniques, the examination scores were found to be normally distributed with mean 20 and sample standard deviation 3. For an independent random sample of 11 students in another introductory finance class that does not use group-learning techniques, the examination scores were found to be normally distributed with mean 38 and standard deviation 2, respectively. Estimate with 90% confidence the difference between the two population mean...
