Question

Determine the lower class boundary for the fifth class.

a) Lower class boundary = Midpoint of the fifth class - Class width/2
b) Lower class boundary = Midpoint of the fifth class + Class width/2
c) Lower class boundary = Midpoint of the fifth class
d) Lower class boundary = Midpoint of the fifth class - Class width

Answer 1

The formula to determine the lower class boundary for the fifth class is: Lower class boundary = Midpoint of the fifth class - Class width/2. Correct option is a.

Step-by-step explanation:

The lower class boundary for the fifth class can be determined using the formula:

Lower class boundary = Midpoint of the fifth class - Class width/2

For example, if the midpoint of the fifth class is 15 and the class width is 5, the lower class boundary would be 15 - 5/2 = 12.5.
