Exercise #7

How does the central limit theorem show us that mean is a good estimator of the population mean (µ)?

 

Choose the BEST answer from the options presented below.

 

 It is the easiest measure of central tendency to calculate on all the separate samples.
The mean of the sampling distribution of the mean is always equal to µ.
The sampling distribution of µ is always close to the sample means.
Infinite sampling from a defined population is always more accurate than random sampling.
