... Show that an unbiased estimate of the population variance is 8.91 ml2 b) Explain why it would be appropriate to use 8.8209 as an estimate of the variance. c) Using 8.91 for the variance construct a 99% confidence interval for the population mean, giving the limits to two decimal places. d) Explain w ...
