17. for the following sample of n = 8 scores: 0, 1, 2, 0, 3,
1.0, and 1:
a. simplify the arithmetic by first multiplying each
score by 2 to obtain a new sample of 0, 2, 1, 0, 6,
1, 0, and 2. then, compute the mean and standard
deviation for the new sample.
b. using the values you obtained in part a, what are
the values for the mean and standard deviation for
the original sample?

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

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
