Question

The sum of lower limit and upper limit of modal class is

$\begin{matrix} W a r r a n t y p e r i o d (y e a r s) & 0 - 1 & 1 - 2 & 2 - 3 & 3 - 4 & 4 - 5 & 5 - 6 N u m b e r o f c o m p o n e n t s & 6 & 10 & 16 & 25 & 16 & 20 \end{matrix}$

Solution

The modal class is the class having maximum frequency. From the above table we can see that the class 3-4 has highest frequency. Therefore , sum of upper limit and lower limit = 7
