1)a. Which two lines represent the critical values?b. Which two lines bound 50% of the probability?c. What specific kind of distribution is this? The image above represents a standard normal distribution curve, which is a bell-shaped graph depicting the distribution of data. The horizontal axis represents z-scores, which indicate the number of standard deviations a data point is from the mean. The vertical axis represents the probability density.### Key Elements of the Graph:- **The Curve:** Symmetrical and centered at zero, indicating that the mean, median, and mode of the data are equal.- **Vertical Lines:** There are six vertical lines labeled A, B, C, D, E, and F, marking specific points on the curve: - **A:** Approximately at -2.5 - **B:** Near -1.5 - **C:** Slightly below -1 - **D and E:** Around 0 (center of the distribution) - **F:** Approximately at 2### Interpretation:- **A, B, C:** Represent negative z-scores, indicating data points below the mean.- **D, E:** At the center, indicating the mean of the distribution.- **F:** Represents a positive z-score, indicating a data point above the mean.### Applications:The normal distribution is frequently used in statistics to represent real-valued random variables with unknown distributions. It is fundamental in various fields such as psychology, business, and natural and social sciences for understanding and interpreting data.
