Question
Look at the histogram given below and answer the question that follow:

$i.$ How many students have height more than or equal to $135\ cm$ but less than $150\ cm?$
$ii.$ Which class interval has the least number of students?
$iii.$ What is the class size?
$iv.$ How many students have height less than $140\ cm?$

Answer

$i.$ Number of students $= 14 + 18 + 10 = 42$
$ii.$ Class interval with least number of students $= 150 - 155$
$iii.$ Class size $= 130 - 125 = 5$
$iv.$ Number of students with height less than $140 = 14 + 8 + 6 = 28$
