Step-by-step explanation:
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
n = 1200
x = 32% of 1200
So, ![\hat{p}=32\5=0.32](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D32%5C5%3D0.32)
We need to find 95% confidence interval.
so, z = 1.96
So, margin of error would be
![z\times \sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.32\times 0.68}{1200}}\\\\=1.96\times 0.0135=](https://tex.z-dn.net/?f=z%5Ctimes%20%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%5C%5C%5C%5C%3D1.96%5Ctimes%20%5Csqrt%7B%5Cdfrac%7B0.32%5Ctimes%200.68%7D%7B1200%7D%7D%5C%5C%5C%5C%3D1.96%5Ctimes%200.0135%3D)
So, Interval would be
![\hat{p}\pm \text{margin of error}}\\\\=0.32\pm 0.0263\\\\=(0.32-0.0263,0.32+0.0263)\\\\=(0.2937,0.3463)\\\\=(0.294,0.346)\\\\=(29.4\%,34.6\%)](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%5Cpm%20%5Ctext%7Bmargin%20of%20error%7D%7D%5C%5C%5C%5C%3D0.32%5Cpm%200.0263%5C%5C%5C%5C%3D%280.32-0.0263%2C0.32%2B0.0263%29%5C%5C%5C%5C%3D%280.2937%2C0.3463%29%5C%5C%5C%5C%3D%280.294%2C0.346%29%5C%5C%5C%5C%3D%2829.4%5C%25%2C34.6%5C%25%29)
Hence, Option 'c' is correct.
