Answer: TRUE
Explanation: Gross Domestic Product ( GDP) can be described as the market value of all goods and services produced in a country within a particular time period which is usually a year.
The equation for finding GDP is given as -
GDP = Consumption + Investment + Government Spending + ( Exports - Imports)
Nominal GDP can be described as the market value of all goods and services produced in a country within a particular time period using current market prices.
Real GDP can be described as the market value of all goods and services produced in a country within a particular time period using base year prices. Using base year prices to calculate real GDP adjusts for inflation.
Where is the statements or answer choices?
Answer:
(a) 2
(b) 2.25
(c) 12.5%
Explanation:
To solve this question we need to remember that
(a) 10 persons produce 160 valves in 8 hours, this implies a productivity of 2=160/(8x10)
(b) 2.25= 180/(8x10)
(c) Percentage change is given by (2.25-2)/2=.125
Answer: mean monthly income = $5000
====================================================
Explanation
In any normal distribution, the median and mean are the same value.
-------------
The proof is as follows:
If mean > median was the case, then the distribution would be skewed to the right (ie positively skewed). The right tail is pulled longer than the left tail. But this would contradict the symmetrical nature of the normal distribution. So mean > median must not be the case.
If mean < median, then the distribution would be skewed to the left (negatively skewed). Visually this pulls the left tail longer than the right tail. Like in the previous paragraph, this contradicts the symmetrical nature of the normal distribution. So mean < median must not be the case.
Since mean > median cannot be true, and neither can mean < median, this must indicate mean = median.
-------------
So in short, any symmetrical distribution always has mean = median and they are at the very center of the distribution.
Goodwill would be unable to measure the standardize tests.
