a simple random sample is drawn from a normally distributed population. the value of which of the following will not be known for certain but can be inferred?\no $mu$\no $\bar{x}$\no $s$\no $n$
Answer
Answer:
A. $\mu$
Brief Explanations:
$\mu$ represents the population mean. When a sample is drawn from a population, the population - mean is usually unknown and has to be inferred. $\bar{x}$ is the sample mean which can be calculated from the sample data. $s$ is the sample standard - deviation which can also be calculated from the sample, and $n$ is the sample size which is known as it is determined when the sample is drawn.
