Given: lowest class boundary = 6.1 Class width = 2.5, Number of classes = 12.2 ⇒ Upper class boundary of the highest class = 6.1 + (2.5 × 12) = 6.1 +30 = 36. 1

Given : lowest class boundary = 6.1
Class width = 2.5, Number of classes = 12.2
$\Rightarrow$ Upper class boundary of the highest class = 6.1 + (2.5 $\times$ 12) = 6.1 +30 = 36. 1
