Answer:
rise by $40 billion
Explanation:
Calculation to determine what the investment will be
Investment=$100 billion*(100%-60%)
=$100 billion*40%
=$40 billion
Therefore the investment will rise by $40 billion
The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample (
) = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) = 
= 
= 
= 11
Hence the standard deviation is equal to 11.
Answer:
False
Explanation:
In a perfectly competitive market the sales revenue is based on pricing also. As the pricing policy also plays an important role in the marketing technique to attract customers.
As the quality served is generally the same in the market, there is no issue in that but when the price is reduced expected sales will increase and accordingly the expected revenue also increases.
As the sales is expected to increase the revenue will also increase accordingly, even though the price is reduced, due to increase in sales quantity the expected change shall not be same as that of the change in price.
Thus, the statement is False.

Answer:
A) sample size = 23.475 ≈ 23
B) How to tell someone to do the test is by taking a sampling process of a lot of the products because this will help to figure out defective units in the line of production and also ensure that the quality of the products are up to the same quality required
Explanation:
Data given
AQL = 20%, = 0.2
LTPD = 52% = 0.52
Assuming consumer risk acceptable by company = 10%
producer risk = 5%
A) First we calculate the ratio
= LTPD / AQL = 0.52 / 0.2 = 2.6
from the table of LTPD/AQL 2.6 is closest to 2.768
to calculate the sample size we apply the formula from the exhibit table
n ( AQL ) = 4.695
Therefore n ( sample size ) = 4.695 / 0.2 = 23.475
B) How to tell someone to do the test is by taking a sampling process of a lot of the products because this will help to figure out defective units in the line of production and also ensure that the quality of the products are up to the same quality required
