<span>2y=-3x+2 |:2
y = -1.5x+1

x=0 </span>⇒ y = -1.5*0 + 1 = 1 A(0; 1)
x=2 ⇒ y = -1.5*2 + 1 = -2 B(2; -2)
x=-2 ⇒ y = -1.5*(-2) + 1 = 4 C(-2; 4)

Answer: 554

Step-by-step explanation:

If prior population proportion is known, then the formula to find the sample size is given by :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

As per given description, we have

p= 0.1

E=0.025

Critical z-value for 95% confidence : $z_{\alpha/2}=1.96$

Then,

$n=0.1(1-0.1)(\dfrac{1.96}{0.025})^2=553.1904\approx554$

Hence, the minimum sample size required = 554.
