Final answer:
The sampling distribution of the mean is an approximate normal distribution. The histogram helps us visualize the shape of the distribution.
Step-by-step explanation:
The sampling distribution of the mean is an approximate normal distribution. This means that if we collect multiple samples of the same size from a population and calculate the mean of each sample, the distribution of those sample means will be approximately normal.
The histogram helps us understand the approximate distribution by visualizing the data. We can plot the sample means on the x-axis and the frequency or probability of each mean on the y-axis. The resulting histogram will show the shape of the distribution and how it approximates a normal curve.
