### Quiz Scores Analysis The following is data for the first and second Quiz scores for 8 students in a class. | First Quiz (Q1) | Second Quiz (Q2) | |-----------------|------------------| | 20 | 17 | | 22 | 21 | | 23 | 20 | | 24 | 20 | | 25 | 24 | | 26 | 21 | | 28 | 27 | | 30 | 28 | ### Instructions: Plot the points on the grid below, then sketch a line that best fits the data. #### Data Plot: - **X-axis (Q1 Scores):** Represents the scores from the first quiz, ranging from 0 to 32. - **Y-axis (Q2 Scores):** Represents the scores from the second quiz, ranging from 0 to 32. - **Plotting Points:** Based on the table, each pair (Q1, Q2) is plotted as a point on the coordinate grid. - Point (20, 17) - Point (22, 21) - Point (23, 20) - Point (24, 20) - Point (25, 24) - Point (26, 21) - Point (28, 27) - Point (30, 28) ### Fitting a Line: After plotting these points, sketch a line that best fits the data. This line should ideally have about as many points above it as below it. ### Prediction: Use the line above to predict the value of the second quiz score if a student had a score of 19 on the first test. Please enter the predicted whole number score for the second quiz in the box provided. --- This practice helps in understanding how to interpret data from tables, plot points on a graph, and derive trends or predictions using a line of best fit.
