Question

the number of students in the tutoring center was recorded for 22 randomly selected times. the data is summarized in the frequency table below.

number of students	frequency
5 - 9	3
10 - 14	0
15 - 19	5
20 - 24	1

what is the class width for this frequency distribution table?

class width = 22 ×

hint: remember, the class width is the distance spanned by each class.

Explanation:

Step1: Identify class limits

Take a class, e.g., 0 - 4. Lower limit = 0, upper limit = 4.

Step2: Calculate class width

Class width = Upper limit - Lower limit = \( 4 - 0 = 5 \). Check another class (5 - 9): \( 9 - 5 = 5 \), same for others.

Answer:

5
