6x+1 = 12x because the Z angles are the same

Solve this and you get:

1 = 12x - 6x => x = 1/6

Answer: 1308

Step-by-step explanation:

Given : Level of confidence = 0.97

Significance level : $\alpha=1-0.97=0.03$

Critical value : $z_{\alpha/2}=2.17$

Margin of error : $E=0.03$

If prior proportion of population is unknown , then the formula to find the population proportion is given by :-

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2$

$\Rightarrow n=0.25(\dfrac{2.17}{0.03})^2=1308.02777778\approx1308$

Hence, the minimum sample size needed =1308
