Textbook Problem

The distribution of sample means is not always a normal distribution. Under what circumstances is the distribution of sample means *not* normal?

To determine

The conditions under which distribution of sample means is not normal.

Explanation

Since, sample means are the representatives of the population means, so as sample size increases, most of the samples piled up closer to the population mean. Therefore, as sample size increases sample means tends to population mean and standard error of sample means decreases...
