Population Distribution
-2.5
The graph at the right show the
frequency distribution of a
population with a population mean of
2.5 and a population standard
deviation of 3.
If samples of size 25 (n = 25) were
taken from the population which
graph would most likely be a good
representation of the distribution of
the sample means?

step-by-step explanation

e2020 got it right

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
