"A country has 50 million people, 30 million of whom are adults. Of the adults, 5 million are not interested in working, another
Pani-rosa [81]

Answer:

There are 20 million people in the labour force.

Step-by-step explanation:

There are 50 million people in the country.

30 million people are adults.

Out of the 30 million, 5 million are not interested in working. Assuming every adult does what he/she wants, then these 5 million are not working. The list then reduces to

30 - 5 = 25 million.

Another 5 million are interested in working but have given up looking for work. The list reduces to

25 - 5 = 20 million.

5 million people are working part time but would like to work full time. They are working, it doesn't matter if it is part time or full time, they are in the labour force.

10 million people are working full time. They are also in the labour force.

THERE ARE 20 MILLION PEOOLE IN THE LABOUR FORCE

Suppose a large labor union wishes to estimate the mean number of hours per month a union member is absent from work. The union
frosja888 [35]

Answer:

The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).

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 M as such

M = z*s

In which s is the standard deviation of the sample.

So

M = 2.575*3.5 = 9.0125

The lower end of the interval is the mean subtracted by M. So it is 7.5 - 9.0125 = -...

There is not a negative number of hours. So the lower end of the interval is 0 hours.

The upper end of the interval is the mean added to M. So it is 7.5 + 9.0125 = 16.5125 hours.

The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).
