Answer 2

The class mark of the given class interval 12 - 25 = 18.5

Step-by-step explanation:

The given class interval = 12 - 25

Here, lower limit = 12 and upper limit = 25

To find, the class mark of the given class interval 12 - 25 = ?

We know that,

The class mark of class interval = $\dfrac{Lower limit+Upper limit}{2}$

= $\dfrac{12+25}{2}$

= $\dfrac{37}{2}$

= 18.5

∴ The class mark of the given class interval 12 - 25 = 18.5

Thus, the class mark of the given class interval 12 - 25 is '18.5'.
