Step-by-step explanation:
class width = upper class limit - lower class limit
= 153-150
= 3
class width of 2nd class = upper limit of second class -lower limit of second class
= 156-153
= 3
class width of 3rd class = upper limit of third class-lower limit of third class
= 159-153
= 3
therefore the class width of this frequency is 3
