Final answer:
The three charts depict the parent population, the sampling distribution of sample means, and their relevance to a random variable 'x' with 'n'.
Step-by-step explanation:
The three charts depict the parent population, the sampling distribution of sample means, and their relevance to a random variable 'x' with 'n'.
The parent population represents the original distribution of the variable 'x'. It is the distribution that we want to study.
The sampling distribution of sample means is a distribution of the means of random samples taken from the parent population. It represents the distribution of the sample means for different sample sizes 'n'.
The relevance of the sampling distribution of sample means to the random variable 'x' with 'n' is that it allows us to make inferences about the population mean using sample means. It provides information about the variability of sample means and how they tend to be distributed around the population mean.
