Answer 1

Answer:

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%

Step-by-step explanation:

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

$\% = \frac{X_i}{n}$

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.
