Answer:

A pie chart

Step-by-step explanation:

A pie chart can simply be used to measure and represent her observation. From the given parameters;

the total number of students = 15

Number of students that said 10pm = 9

using the pie chart; we take each measure to be fraction of the angles in a circle.

Angle subtended by the 9 students =
(9)/(15) x 360 = 216°
