Question

the consecutive class marks of a distribution are 37,42,47,52,57. Determine the class size and the class limits corresponding to the last class mark.​

Answer 1

Lower class mark = 37 Upper class mark = 57 Range = 57 - 37 = 20 Let the number of classes be 4. Therefore, size of the class = 20/4 = 5. Class limits are 36 - 40, 41 - 45, 46 - 50, 51 - 55, 56 - 60.

i hope this helps u ;)

Answer 2

$here \: is \: ur \: answer$

$lower \: class \: mark \: \: = 37$

$upper \: class \: mark \: = 57 \: range$

$57 - 37 = 20$

$let \: the \: number \: of \: classes \: be \: 4$

$therefore \: the \: size \: of \: the \: class \:$

$= 20 \4 = 5.$

$class \: limits \: \: are \: 36 - 40.41 - 45. \: 46 - 50.51 - 55 \: 56 - 60$

$hop \: it \: helps \: u$

$belieber \: forever$
