Sample size=n=250
sample proportion=p=0.4
95% confidence interval so significance level α=1-0.95=0.05
So, α/2=0.025
z_( α/2)=1.960 (value taken from statistic z-table)
use formula;

p(+/-)z_(α/2)square root(p(1-p)/n)

(0.4-1.960 sq.root(0.4(1-0.4)/250), 0.4+1.960 sq.root(0.4(1-0.4)/250))

<h2>a.</h2><h3>Solution:</h3>

$42 - 42 \times 15\%$

$=42 - 42 \times \frac{15}{100}$

$=42 - 21 \times \frac{15}{50}$

$=42 - \frac{315}{50}$

$= 42 - 6 \: \frac{15}{50}$

$= 41 \: \frac{50}{50} - 6 \: \frac{15}{50}$

$= 35 \: \frac{35}{50}$

$= 35.70$
