Question

Find the z-score boundaries that separate a normal distribution as described in each of the following:

a) The middle 30% from the 70% in the tails

b) The middle 40% from the 60% in the tails

c) The middle 50% from the 50% in the tails

d) The middle 60% from the 40% in the tails

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.
