A population of values has a normal distribution with μ=134μ=134 and σ=59.9σ=59.9. You intend to draw a random sample of size n=184n=184.

Find P₃₅, which is the score separating the bottom 35% scores from the top 65% scores.
P₃₅ (for single values) =

Find P₃₅, which is the mean separating the bottom 35% means from the top 65% means.
P₃₅ (for sample means) =

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.
