Allisa [31]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

n = 1200

x = 32% of 1200

So, $\hat{p}=32\5=0.32$

We need to find 95% confidence interval.

so, z = 1.96

So, margin of error would be

$z\times \sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.32\times 0.68}{1200}}\\\\=1.96\times 0.0135=$

So, Interval would be

$\hat{p}\pm \text{margin of error}}\\\\=0.32\pm 0.0263\\\\=(0.32-0.0263,0.32+0.0263)\\\\=(0.2937,0.3463)\\\\=(0.294,0.346)\\\\=(29.4\%,34.6\%)$

Hence, Option 'c' is correct.

The perimeter of a rectangular window is 264 cm.

german

Answer:

length = 76 cm

Step-by-step explanation:

The perimeter = (2 × width) + (2 × length)

264 = (2×56) + (2 × length)

264 = 112 + (2 × length)

264 - 112 = 2 × length

152 = 2 × length

152/2 = length

76 = length

length = 76 cm
