Answer:
C. Decreases the margin of error and hence increases the precision
Step-by-step explanation:
If we select a sample by Simple Random Sampling in a population of “infinite” size (a population so large that we do not know its size exactly), then the margin of error is given by
where
<em>Z = The Z-score corresponding to the confidence level </em>
<em>S = The estimated standard deviation of the population </em>
<em>n = the size of the sample. </em>
As we can see, since n is in the denominator of the fraction and the numerator is kept constant, the larger the sample size the smaller the margin of error, so the correct choice is:

Given that <span>work hours in new zombie are 200 in year 1 and productivity is $8
per hour worked.
The new zombie's real gdp in year 1 is given by 200 x $8 = $1,600
If work hours increase to 210 in year 2 and productivity rises to $10 per hour.
The new zombie's real gdp in year 2 is given by 210 x $10 = $2,100
The new zombie's rate of economic growth is given by
