Question

What is true about populations?

Group of answer choices

The population is everyone who is relevant to answering the research question.

Populations are of infinite size.

The standard deviation of a population is generally larger than the standard deviation of a sample.

The population can be approximated with a normal distribution as long as samples are larger (over 25).

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
