Answer:
Therefore the answer is 20.
Step-by-step explanation:
We know that
class interval = range / number of classes
But here number of classes is not given , so we use the formula
class interval = range / ( 1+ 3.322 log N)
where , range =maximum - minimum = 220-100 = 120
N= number of observations = 50
class interval = 120 / ( 1+ 3.322 * log 50) = 18.06
Rounding up to a convinient number
Thus , class intervai = 20
Therefore the answer is 20.

Substitute:
The percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.
<h3>What is the percentage?</h3>
The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
It is given in the question that the number of students in the marching band increased from 100 to 125 so we need to find the percentage increase of the students.
The percentage increase of the students will be calculated as:-
% increase=[(125-100)÷(100)]x100
% increase=[(25)÷(100)]x100
% increase= [0.25x100]
% increase= 25%
Hence the percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.
