Answer 2

$\underline{\pink{ Class \:size :}}$

The difference between the true upper limit and true lower limit of a class interval is called the class size.

$Given \: class \:interval \: (150 - 170)$

$\red{Class \:size\:of \:class \:interval}$

$\green {= actual \:upper \:limit - actual \:lower \:limit }$

$= 170 - 150$

$= 20$

Therefore.,

$\red{Class \:size\:of \:class \:interval\:150-170}$

$\green { = 20}$
