Determine the percentage of off-campus students
From the above table, we have that:
[tex]Off-Campus = 182[/tex]
[tex]Total\ Surveyed = 400[/tex]
The percentage is then calculated as follows;
[tex]\%Off-Campus = \frac{Off-Campus}{Total-Surveyed} * 100\%[/tex]
[tex]\%Off-Campus = \frac{182}{400} * 100\%[/tex]
[tex]\%Off-Campus = 0.455 * 100\%[/tex]
[tex]\%Off-Campus = 45.5\%[/tex]
Hence, option C answers the question
