A professor has recently taught two sections of the same coursewith only one difference between the sections. In one section, heused only examples taken from sports applications, and in the othersection, he used examples taken from a variety of applicationareas. The sports themed section was advertised as such; sostudents knew which type of section they were enrolling in. Theprofessor has asked you to compare student performance in the twosections using course grades and total points earned in the course.You will need to import the Scores.csv dataset that has beenprovided for you:

Use the appropriate R functions to answer the followingquestions:
1. What are the observational units in this study?
2. Identify the variables mentioned in the narrative paragraphand determine which are categorical and quantitative?
3. Create one variable to hold a subset of your data set thatcontains only the Regular Section and one variable for the SportsSection.
4. Use the Plot function to plot each Sections scores and thenumber of students achieving that score. Use additional PlotArguments to label the graph and give each axis an appropriatelabel. Once you have produced your Plots answer the followingquestions:
a. Comparing and contrasting the point distributions between thetwo section, looking at both tendency and consistency: Can you saythat one section tended to score more points than the other?Justify and explain your answer.
b. Did every student in one section score more points than everystudent in the other section? If not, explain what a statisticaltendency means in this context.
c. What could be one additional variable that was not mentionedin the narrative that could be influencing the point distributionsbetween the two sections?
