From a stand of eucalyptus, 25 trees were drawn and their diameters were determined, in cm, in order to estimate the mean diameter of the stand. These diameters were: a) Based on this sample, calculate the 90% and 95% confidence intervals for the population mean. b) Obtain the 95% confidence interval for population variance.

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
