A 95% confidence interval for a population mean u is given as (17.3, 22.7). This confidence interval is based on a simple random sample of 33 observations. Calculate the sample mean and sample standard deviation. Assume that all conditions necessary for inference are satisfied. Use the Excel function t.inv as necessary to obtain values from the t-distribution in any calculations and give all answers to 3 decimal places. Sample Mean = Sample Standard deviation =
