For the following scores,| X | Y ||----|----|| 7 | 6 || 9 | 6 || 6 | 3 || 12 | 5 || 9 | 6 || 5 | 4 |Using the Graphs tool below, sketch a scatter plot showing the six data points.**Scatter plot explanation:**The scatter plot displays points on a two-dimensional graph, representing the relationship between the X and Y values. - The X-axis ranges from 5 to 12.- The Y-axis ranges from 3 to 7.- Six points are plotted corresponding to the pairs of X and Y values given in the table.- The points are distributed such that some X values have the same Y values, resulting in overlapping on the Y-axis. Specifically, the points for (7, 6) and (9, 6) appear close together. The image contains a scatter plot and elements related to Pearson correlation analysis, intended for educational purposes.### Scatter Plot Description:- The graph has points scattered around a trend line. The line has a direction that shows it is sloping downwards to the left. - The x-axis is labeled as "X" with values ranging from 0 to 14.- The y-axis is labeled as "Y" with values ranging from 0 to 14.### Estimating Pearson Correlation:- The task is to estimate the value of the Pearson correlation by observing the scatter plot.- Options provided are: 1. The correlation is small but positive; around 0.8 to 1.0. 2. The correlation is small but positive; around 0.4 to 0.6. 3. The correlation is small but negative; around -0.4 to -0.7.### Table for Calculating Pearson Correlation:- There is a table with empty fields for calculations related to Pearson correlation: - ΣX² (Sum of X squared) - ΣY² (Sum of Y squared) - ΣXY (Sum of the product of X and Y) - SSₓ (Sum of squares of X) - SSᵧ (Sum of squares of Y) - SP (Sum of products)### Compute the Pearson Correlation:- There is a blank space to compute and write down the Pearson correlation value.This educational resource helps students learn how to visually estimate and calculate Pearson correlation from given data.
