A simple random sample is drawn from a population denoted B, with population mean mg and population variance 0%.The following sample statistics were obtained: Sample B Sample size: n 60 Sample mean: g 11.5 Sample variance: 0% 4.3 where g is the sample mean estimator and 6% is the sample variance estimator. Making clear any assumptions you make, obtain the upper bound for a 99% condence interval for #3
