Reference no: EM13638335

A 95% confidence interval for a population mean, u, is given as (18.958, 21.015). This confidence interval is based on a simple random sample of 36 observations. Calculate the sample mean, standard deviation, and margin of error. Assume that all conditions necessary for inference are satisfied. Use the t distribution in any calculations.
