**Title: Understanding the Normal Distribution Curve****Text:**The graph of a normal curve is given. Use the graph to identify the value of μ (mu) and σ (sigma).**Diagram Explanation:**- The graph depicted is a bell-shaped curve, which is characteristic of a normal distribution.- The x-axis is labeled with values ranging from -6 to 10.- The highest point of the curve is centered at 2 on the x-axis.- This indicates that the mean (μ) of the distribution is 2.- The spread of the curve shows that it is 4 units wide on either side of the mean, suggesting that the standard deviation (σ) is 4.**Questions:**- The value of μ is [2].- The value of σ is [4].This brief tutorial helps in identifying the mean and standard deviation from a normal distribution graph, enhancing comprehension of basic statistical concepts.
