A 90% confidence interval for a population mean, μ, is given as (21.73, 24.64). This confidence interval is based on a simple random sample of 41 observations. Calculate the sample mean and standard deviation. Assume that all conditions necessary for inference are satisfied. Use the t- distribution in any calculations.

This is a question regarding Statistics. Calculate and interpret a confidence interval for a population mean. given a normal distribution with 1) a known variance2) an unknown population variance or 3) an unknown variance and a large sample size when sampling from a normal distribution, why test statistic no matter small(n<30) or large(n>=30) we choose z-statistic?(please give an example) Thanks
