Question

Write the class limits in 10.4,11.4,12.4

Answer 1

The class limits are "10.9 and 11.9".

Step-by-step explanation:

We have,

10.4, 11.4, 12.4

To find, the class limits = ?

We know that,

The class limits =$\dfrac{Upper limit+Lower limit}{2}$

Take = 10.4, 11.4,

Lower limit = 10.4 and upper limit = 11.4

∴ The class limits $=\dfrac{10.4+11.4}{2}=\dfrac{21.8}{2} =10.9$

Take = 11.4, 12.4

Lower limit = 11.4 and upper limit = 12.4

∴ The class limits $=\dfrac{11.4+12.4}{2}=\dfrac{23.8}{2} =11.9$

Hence, the class limits are "10.9 and 11.9".
