Question

the weights of five children in a group are 25 ,35, 35 ,28 ,and 32. find their mean weight and median weight .after a year was found that they all gain 3kg each find the new mean weight​

Answer 1

Answer:

31,32,34

Step-by-step explanation:

SUM OF OBSERVATIONS = (25+35+35+28+32)=155

NUMBER OF OBSERVATIONS= 5

THEREfORE, MEAN=155/5=31

ARRANGING IN ASCENDING ORDER,

25,28,32,35,35

MEDIAN= (n+1)/2 th observation = 3rd observation= 32

as we know, total increases when equal is added to each no

mean(new)=31+3=34
