Question

Provide an appropriate response. Use the Standard Normal Table to find the probability.

IQ test scores are normally distributed with a mean of

and a standard deviation of

16.

An individual's IQ score is found to be

118.

Find the z-score corresponding to this value. Round the answer to the nearest hundredth.

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.
