1.645sqrt((0.5(1-0.5))/n)<0.04

1.645 \frac{0.5 ( 1 - 0.5 )}{n} < 0.04

\frac{0.25}{n} < \frac{0.0016}{2.706025}

Solution steps

1.645 \frac{0.5 ( 1 - 0.5 )}{n} < 0.04

Divide both sides by

1.645

\frac{1.645 \frac{0.5 ( 1 - 0.5 )}{n}}{1.645} < \frac{0.04}{1.645}

Simplify

\frac{0.5 ( 1 - 0.5 )}{n} < \frac{0.04}{1.645}

Square both sides

(\frac{0.5 ( 1 - 0.5 )}{n})^{2} < (\frac{0.04}{1.645})^{2}

Simplify

\frac{0.25}{n} < (\frac{0.04}{1.645})^{2}

Expand

(\frac{0.04}{1.645})^{2} : \frac{0.0016}{2.706025}

\frac{0.25}{n} < \frac{0.0016}{2.706025}

\frac{0.25}{n} < \frac{0.0016}{2.706025} : n < 0 or n > \frac{0.67650625}{0.0016}

n < 0 or n > \frac{0.67650625}{0.0016}
