Question

The scores on a creativity test of 400 interior designers are found to be normally distributed with a mean of 76 and a standard deviation of 4. Using the 50%-34%-14% figure (given here), compute the following:

3.1. What is the minimum Z score an interior designer can have on the creativity test to be in the top of the given percentages?

3.1.1. 50%

3.1.2. 16%

3.1.3. 84%

3.2. What is the minimum raw score an interior designer can have on the creativity test to be in the top of the given percentages?

3.2.1. 50%

3.2.2. 16%

3.2.3. 84%

3.3. What is the minimum raw score an interior designer can have on the creativity test to be in the top 16%?

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.
