Answer 1

hey mate here is ur answer

Any chance done to observation will be directly applied to mean.

a)Divided by 5.

So mean will also get divided by 5.

new mean = 35/5=7

b)divided by 7.

So mean will also get divided by 7

new mean =35/7=5.

c)Increased by 8.

Mean will also increase by 8.

new mean = 35+8=43

d)Decreased by 4.

mean will also get decreased by 4.

new mean = 35-4=31.

hope it helps.
