    Suppose the 90% confidence interval for the mean SAT scores of applicants at a business college is given by [1,694, 1,836]. This confidence interval uses the sample mean and the sample standard deviation based on 25 observations. [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? (Round "t" value to 3 decimal places and “Sample mean” and "Sample standard deviation" to 2 decimal places.)
