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:
Answer:
correct option is A. True
Explanation:
given data
economy grows = 3 percent
total factor productivity grows = 2 percent
labor force grows = 2 percent
labor contributes = 40 percent
stock of capital rise = 0.33 percent
solution
we apply here Economy growth % formula that is
Economy growth % = total factor productivity + labor contributes × labor force grows + ( 1- labor contributes ) stock of capital .............1
put here value
3% = 2% + 40% (2%) + 60% C
3% = 2.8 + 0.6 × C
C =
C = 33.33 %
so given statement is true
