Answer:

(\frac{2}{5} ) {}^{ - 3}  \\  =  (\frac{a}{b} ) {}^{ - x}  =  (\frac{b}{a} ) {}^{x}  \\  so  \:  \:  \:  \:  \:  \:  (\frac{2}{5} ) {}^{ - 3}  \\  =  (\frac{5}{2} ) {}^{3}  \\  =   \frac{5 {}^{3} }{2 {}^{3} }  \\  \:  = \:    \frac{125}{8}

Increasing the sample size while keeping the same confidence level has what effect on the margin of error? A. Increases the marg
DiKsa [7]

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

\bf E=\frac{ZS}{\sqrt{n}}

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:

C. Decreases the margin of error and hence increases the precision
