To convert radians to degrees multiply by 180/pi

so 4 rads = (180* 4) / pi degrees

Answer:

4radians= $229.29degress$

Step-by-step explanation:

We have to convert radians to degrees, thus in order to convert radins to degree, the radians should be multiplied with $\frac{180}{\pi}$ .

Thus, conversion of 4radians to degrees is as follows:

4radians= $4{\times}\frac{180}{\pi}$

Using the value of π=3.14, get

4radians= $4{\times}\frac{180}{3.14}$

4radians= $4{\times}57.32$

4radians= $229.29degress$

Answer:

The minimum sample size required to create the specified confidence interval is 2229.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.99}{2} = 0.005$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.005 = 0.995$ , so $z = 2.575$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

What is the minimum sample size required to create the specified confidence interval

This is n when $M = 0.06, \sigma = 1.1$

$0.06 = 2.575*\frac{1.1}{\sqrt{n}}$

$0.06\sqrt{n} = 2.575*1.1$

$\sqrt{n} = \frac{2.575*1.1}{0.06}$

$(\sqrt{n})^{2} = (\frac{2.575*1.1}{0.06})^{2}$

$n = 2228.6$

Rounding up

The minimum sample size required to create the specified confidence interval is 2229.
