Answer:
We know that,
Mean= totalstudents
___________
totalno.sum
= 30+31+34+34+34+36+37+38+38+45+50/11
= 407/11
=37
Step-by-step explanation:
Range = highest value - least value
= 50-31 = 19
arithmetic mean = sum of values / no.of values
sum of values= 34 +37+38+50+34+34+38+38+36+45+31 =377
arithmetic mean =415/11 = 37.72
median = 36
