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

bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
quick note:
the "x" must not have a negative coefficient for the standard form, though in this case it shows like so in the inappropriate choices above.
