Answer:The required interval is (0.196, 0.030).

Step-by-step explanation:

Since we have given that

n = 432

x = 108

So, $\hat{p}=\dfrac{x}{n}=\dfrac{108}{432}=0.25$

at 99% level of confidence, z = 2.576

So, Margin of error would be

$z\times \sqrt{\dfrac{pq}{n}}\\\\=2.576\times \sqrt{\dfrac{0.25\times 0.75}{432}}\\\\=2.576\times 0.021\\\\=0.0536$

So, margin of error = 0.0536

Now, confidence interval would be

$\hat{p}\pm 0.0536\\\\=(0.25-0.0536,0.25+0.0536)\\\\=(0.1964,0.3036)\\\\\approx (0.196,0.030)$

Hence, the required interval is (0.196, 0.030).

Degger [83]

Answer:

$V = 997.8 {cm}^{3}$

Step-by-step explanation:

The last one is spherical

The volume of a sphere is given by:

$V= \frac{4}{3} \pi \: {r}^{3}$

From the diagram, the the radius is r=6.2 cm.

We substitute to get:

$V= \frac{4}{3} \times 3.14\: \times {6.2}^{3}$

This evaluate to;

$V = 997.8 {cm}^{3}$
