Burka [1]

Answer:

7.07

Step-by-step explanation:

Angle M is 63 degrees because all 3 angles must add to 180.  

Now use the law of sines:  

sin(90)/x = sin(63)/6.3  

Cross multiply: 6.3 sin (90) = x sin (63)  

Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x

An economist wants to estimate the mean income for the first year of work for college graduates who have had the profound wisdom
suter [353]

Answer:

We need at least 601 incomes.

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{1-0.95}{2} = 0.025

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 1-0.025 = 0.975, so z = 1.96

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.

How many such incomes must be found if we want to be 95% confident that the sample mean is within $500 of the true population mean?

We have to find n, for which M = 500, \sigma = 6250. So

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

500 = 1.96*\frac{6250}{\sqrt{n}}

500\sqrt{n} = 1.96*6250

\sqrt{n} = \frac{1.96*6250}{500}

(\sqrt{n})^{2} = (\frac{1.96*6250}{500})^{2}

n = 600.25

Rounding up

We need at least 601 incomes.
