GrogVix [38]

Answer: 235

Step-by-step explanation:

The formula to calculate the sample size  :-

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

Given :  Estimated proportion \hat{p}=0.89

Margin of error : E=0.04

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2} =1.96

Now, the required sample size will be :-

n=(0.89(0.11))(\dfrac{(1.96)}{0.04})^2

\Rightarrow\ n= 235.057\approx235

Hence, the required minimum sample size = 235

Step-by-step explanation:

The midpoint M is then defined by M = ((x + X)/2,(y + Y)/2)
