8 classes

Step-by-step explanation:

Given

Least = 2403

Highest = 11998

n = 225

Required

The number of class

To calculate the number of class, the following must be true

2^k n

Where k is the number of classes

So, we have:

2^k 225

Take logarithm of both sides

$\log(2^k) \log(225)$

Apply law of logarithm

$k\log(2) \log(225)$

Divide both sides by log(2)

$k \frac{\log(225)}{\log(2)}$

k 7.8

Round up to get the least number of classes

k = 8
