There are 800 students in the School of Business Administration. There are four majors in the School: Accounting, Finance, Management, and Marketing. The following shows the number of students in each major.

col1 Major Accounting Finance Management Marketing
col2 Number of Students 240 160 320 80
Develop a percent frequency distribution and construct a pie chart.

Answer 1

Major
`X_i` %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%

_________________________________________

Total 800 100%

Explanation:

For this case we can create the following table calculating the percent frequency as:

`\% = (X_i)/(n)`

Where
`X_i` represent the number of students for the i category and n the total sample size.

Major
`X_i` %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%

_________________________________________

Total 800 100%

The pie chart is on the figure attached. We use excel to create it.
