Question
Construct a frequency table for the following weights $($in $gm)$ of $35$ mangoes using the equal class intervals, one of them is $40-50$ ($45$ not included):
$30, 40, 45, 32, 43, 50, 55, 62, 70, 70, 61, 62, 53, 52, 50, 42,$
$ 35, 37, 53, 55, 65, 70, 73, 74, 45, 46, 58, 59, 60, 62, 74, 34, 35, 70, 68$.
$i.$ What is the class mark of the class interval $40-45$?
$ii.$ What is the range of the above weights?
$iii.$ How many classes are there?
$30, 40, 45, 32, 43, 50, 55, 62, 70, 70, 61, 62, 53, 52, 50, 42,$
