Answer:
Answer is option A, i.e. systematic sampling.
Explanation:
Systematic sampling is the type of probability sampling method of selection of samples out of the given group of homogenous nature. In this method, every Kth sample is selected until the required amount is obtained. Here, Chrysler selects every 16th van until he is successful in obtaining the 80 vans. Thus, Chrysler is using a systematic sampling method here.
The waiting time at which 10 percent of the people would continue to hold is given as 2.3
<h3>How to solve for the waiting time</h3>
We have to solve for X ~ Exponential(λ).
then E(X) = 1/λ = 3,
= 0.3333
Remember that the cumulative distribution function of X is F(x) = 1 - e^(-λx). ; x is equal to the time in over case
For 10 percent of the people we would have a probability of
10/100 = 0.1
we are to find
P(X ≤ t)
= 1 - e^(0.3333)(t) = 0.1
Our concern is the value of t
Then we take the like terms
1-0.1 = e^(0.3333)(t)
1/0.9 = e^(0.3333)(t)
t = 3 * ln(1/0.9)
= 0.3157
Money supply is the total amount of money in circulation which includes coins, cash and balance in savings account in a country at a period of time.
- Given a fixed supply of money and a downward sloping aggregate demand curve, an increase in money demand will <u>not change</u> the price paid for its use, otherwise known as the <u>discount rate.</u>
- A change the money supply in a country causes a change in aggregate demand.
- An increase in the money supply causes increase in aggregate demand and a decrease in the money supply causes decrease in aggregate demand.
Therefore, an increase in money demand will not change the price paid for its use, otherwise known as the discount rate.

Answer:
Quantity of beef demanded will decrease by 12%
Explanation:
Data provided in the question:
Price elasticity of demand for beef, Ed = 0.60
Increase in the price of beef = 20%
Now,
Price elasticity of demand for beef,
Ed = [ Percentage change in Quantity ] ÷ [ Percentage change in price ]
or
0.60 = [ Percentage change in Quantity ] ÷ 20%
or
Percentage change in Quantity = 0.60 × 20%
or
Percentage change in Quantity = 12%
Also,
Price and Quantity are inversely proportional
Hence,
With the increase in price, the quantity will decrease
Therefore,
Quantity of beef demanded will decrease by 12%
