If we consider the simple random sampling process as an experiment, the sample mean is a. a random variable. b. always zero. c.
1 answer:
The sample mean is an estimate of the population mean.
The sample mean is exactly equal to the population mean
<h3>How to determine the true statement</h3>
When the population mean is known; the value of the population mean can be used as the sample mean.
This is so because:
The sample mean is an estimate of the population mean.
And it is represented as:
Hence, the true statement is that the sample mean is exactly equal to the population mean

You have to consider the “ends” of the x-axis, the far right (for infinitely large values of x) and left (for infinitely small values of x) of the graph.
From the diagram above you can see that:
- When
then
(notice that as the values of x get smaller and smaller, the graph gets closer and closer to the line y=1);
- When
then
(notice that as the values of x get larger and larger, the graph gets closer and closer to the line y=1).
