Answer 2

The class mark of class interval 6 - 7 is equal to 6.5.

Step-by-step explanation:

Given,

Class interval 6 - 7

Here, lower limit = 6 and upper limit = 7

To find, the class mark of class interval 6 - 7 = ?

We know that,

∴ Class mark = $\dfrac{Lower limit+Upper limit}{2}$

= $\dfrac{6+7}{2}$

$=\dfrac{13}{2}$

= 6.5

∴ The class mark of class interval 6 - 7 = 6.5

Thus, the class mark of class interval 6 - 7 is equal to 6.5.
