To determine the best fit undergraduate program, a high school senior researches the majors offered at the universities he is considering for admissions. The internet search reports that Arizona State University lists nine of their most popular majors and the percent of the student population enrolled in the programs.
Popular Majors Percent of Student body
Biology 8%
Business Marketing 20%
Communications/Journalism 6%
Education 5%
Engineering 7%
Interdisciplinary Studies 6%
Psychology 6%
Social Sciences 10%
Visual and Performing Arts 8%

Create a scatter plot of the data represented in the table of teachers’ salaries. Be sure to include all appropriate labels.
Use the scatter plot created for question #1 to write a line of best fit in the slope-intercept form for the data. In your final answer, include all necessary calculations.
For the equation of the line best fit, predict the national average teachers’ salary for the year 2014. In your final answer, include all necessary calculations.
To create a circle graph and a bar graph representing the university's expected student enrollment according to major, you will need to follow these steps:
1. Calculate the number of students expected to enroll in each major based on the given percentages and the total enrollment of 22,000 students.
Biology: 8% of 22,000 = 0.08 * 22,000 = 1,760 students
Business Marketing: 20% of 22,000 = 0.20 * 22,000 = 4,400 students
Communications/Journalism: 6% of 22,000 = 0.06 * 22,000 = 1,320 students
Education: 5% of 22,000 = 0.05 * 22,000 = 1,100 students
Engineering: 7% of 22,000 = 0.07 * 22,000 = 1,540 students
Interdisciplinary Studies: 6% of 22,000 = 0.06 * 22,000 = 1,320 students
Psychology: 6% of 22,000 = 0.06 * 22,000 = 1,320 students
Social Sciences: 10% of 22,000 = 0.10 * 22,000 = 2,200 students
Visual and Performing Arts: 8% of 22,000 = 0.08 * 22,000 = 1,760 students
2. Create a circle graph:
a. Determine the central angle for each major by dividing the number of students expected in that major by the total number of students (22,000) and multiplying by 360 degrees.
b. Draw a circle and divide it into sectors according to the calculated central angles for each major.
c. Label each sector with the respective major and its percentage or number of students.
3. Create a bar graph:
a. Draw a horizontal or vertical axis and label it "Major" on the y-axis (vertical) and "Number of Students" on the x-axis (horizontal).
b. Create bars for each major using their respective number of students as the height of the bars.
c. Label each bar with the respective major.
Remember to use a suitable scale for the bar graph to ensure that the bars are appropriately sized and distinguishable from one another.
These steps should help you create both a circle graph and a bar graph representing the university's expected student enrollment according to major.
