Question

Creating a visual representation here is challenging, but I can guide you on how to label key points on the symmetric bell-shaped graph with a mean of 510 and a standard deviation of 91: 1. **Mean (Peak)**: The highest point on the graph corresponds to the mean, which is 510 in this case. 2. **± 1 Standard Deviation**: Mark points on both sides of the mean at a distance of 91 units (standard deviation). These points would be at \(510 + 91\) and \(510 - 91\). 3. **± 2 Standard Deviations**: Similarly, mark points at \(510 + (2 \times 91)\) and \(510 - (2 \times 91)\) to represent values within 2 standard deviations from the mean. 4. **± 3 Standard Deviations**: Repeat the process for values within 3 standard deviations from the mean, at \(510 + (3 \times 91)\) and \(510 - (3 \times 91)\). Label each of these points on the x-axis, and you'll have a well-labeled symmetric bell-shaped graph representing the normal distribution with a mean of 510 and a standard deviation of 91.

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.
