Suppose the 90% confidence interval for the mean SAT scores of applicants at a business college is given by [1,691, 1,838]. This confidence interval uses the sample mean and the sample standard deviation based on 25 observations. Use t value 1.711 in your calculations. [You may find it useful to reference the t table.] What are the sample mean and the sample standard deviation used when computing the interval?
