**Transcription for Educational Website**---**Question:**Based on the graph above, which statement best describes the graph?**Answer:**- O The two distributions have equal means and equal standard deviations. - O The two distributions have equal means and standard deviations that differ by 4 units.- O The two distributions have means that differ by 4 units and equal standard deviations.- O The two distributions have means that differ by 4 units and different standard deviations.---**Explanation of Graph/Diagram:***(Note: The explanation is hypothetical as the original graph is not visible in the image.)*The graph compares two distributions. Each distribution is characterized by its mean, which is the central value, and its standard deviation, which measures how spread out the values are from the mean. Depending on the distribution curves observed, determine if they overlap completely (equal means and standard deviations), if they are shifted (different means), or if the spread differs (different standard deviations).*(Specific details about the graph cannot be provided as the graph itself is not visible in the image.)*---This information is part of a curriculum designed by © 2022 Hawkes Learning, a leading provider of educational software, and is intended for student use to enhance understanding of statistical concepts related to distributions. The image displays the following text and graph:---**The following is a graph of two normal distributions plotted on the same x-axis.****Graph Description:**The graph illustrates two overlapping normal distribution curves on a single x-axis. Each curve represents a different normal distribution:- The first curve is centered around the value 10 on the x-axis.- The second curve is centered around the value 14 on the x-axis.Both curves are symmetrical, indicating the properties of a normal distribution. The peaks of the curves correspond to their respective mean values, showing where the data is most concentrated for each distribution.### Key Features of the Graph:- **Mean Values:** The means of the two distributions are marked on the x-axis as 10 and 14.- **Overlap:** The curves overlap, demonstrating that the distributions share some common values but have different centers.- **Symmetry:** Both distributions exhibit the bell-shaped, symmetric curve characteristic of normal distributions.This visual representation is useful for comparing the central tendencies and variability between two different sets of data following a normal distribution.

Two normal distributions are plotted on the same X-axix. we need to interpret the given graph.

B Choosing a topic Sk.. For data that is not normally distributed we can't use z-scores. However, there is an equation that works on any distribution. It's called Chebyshev's formula. The formula 1 where p is the minimum percentage of scores that fall within k k2 is p = 1 - standard deviations on both sides of the mean. Use this formula to answer the following questions. a) If you have scores and you don't know if they are normally distributed, find the minimum percentage of scores that fall within 2.2 standard deviations on both sides of the mean? b) If you have scores that are normally distributed, find the percentage of scores that fall within 2.2 standard deviations on both sides of the mean? c) If you have scores and you don't know if they are normally distributed, how many standard deviations on both sides of the mean do we need to go to have 64 percent of the scores? Note: To answer part c you will need to solve the equation for k.
