Answer 2

Answer:

New mean=75

Step-by-step explanation:

Value of 100 observations=24*100=2400

Now 6 is added to each of the observations

Then value=2400+6*100=3000

Now all the items are multiplied by 2.5

then value will become=3000*2.5

So then new mean

=total value/ No of observations

=2.5*3000/100

=7500/100

=75
