Final answer:
To create a line plot for the radio quiz show scores, they must be ordered numerically and the frequency of each score is then marked on the plot. The question cannot be fully answered without additional class data for comparison.
Step-by-step explanation:
The question requires an understanding of how to organize and represent data graphically. Students must extract scores from a list and plot them on a line plot to visualize the frequency of each score. A line plot is a simple graph that shows the frequency of data occurring along a number line. When creating a line plot, each score is marked with an 'X' above the corresponding value on the plot.
To graph the scores correctly, the student must first organize the scores in numerical order. Then, count the frequency of each score and place the appropriate number of 'X's above that score's value on the line plot. To find whose score was the best compared to their own class, numerical justification is needed which typically involves comparing scores to the class average or using percentile ranking. Without additional context or data on the rest of the class's scores, this task cannot be completed with the given information.
A line plot is a graph that uses Xs or any icon to display the number of times a response has been recorded in a particular set of data. The Xs are generally placed along with the responses.
