expand 0.8\pm 1.96sqrt((0.8(1-0.8))/(50))

expand

0.8 \pm 1.96 \frac{0.8 ( 1 - 0.8 )}{50}

0.8 \cdot 1.96 \cdot \frac{0.4}{5 2} \pm

Solution steps

0.8 \pm 1.96 \frac{0.8 ( 1 - 0.8 )}{50}

Apply radical rule:

\frac{a}{b} = \frac{a}{b}

\frac{0.8 ( 1 - 0.8 )}{50} = \frac{0.8 ( 1 - 0.8 )}{50}

= 0.8 \cdot 1.96 \cdot \frac{0.8 ( 1 - 0.8 )}{50} \pm

0.8 (1 - 0.8) = 0.4

= 0.8 \pm 1.96 \cdot \frac{0.4}{50}

50 = 52

= 0.8 \pm 1.96 \cdot \frac{0.4}{5 2}

\frac{x ^{2}}{a ^{2}}

(2 x)^{3}

(20)^{2}

(2 x) (4 x^{2})
