Suppose the civilian noninstitutionalized working-age population is 35.9 million in in a hypothetical economy. Of these, 4.9 mil
1 answer:
Answer:
Total no. of people employed:
= No. of people working part-time + No. of people working full time
= 4.9 million + 14.53 million
= 19.43 million
Total no. of people unemployed:
= People in the working age population who are not working and have looked for work in the past four weeks
= 2.90 + 1.72 million
= 4.62 million
Labor force = Total no. of people employed + Total no. of people unemployed
= 19.43 million + 4.62 million
= 24.05 million
Labor force participation rate:
= 0.6699
= 66.99%
Unemployment rate:
= 0.1920
= 19.20%

Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
