What requirements must be satisfied? Select all that apply.

A. Either the population is normally distributed, or n > 30, or both.
B. At least one observation must be above or below 80 sec.
C. The sample observations must be a simple random sample.
D. The conditions for a binomial distribution must be satisfied.

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.
