I think you’re right because I put the same thing on my quiz
7.003 has the least value of all the choices given
Answer: (0.504, 0.556)
Step-by-step explanation:
Given : Sample size : n= 1005
Number of adults stated that they were worried about having enough money to live comfortably in retirement = 531
Then the proportion of adults stated that they were worried about having enough money to live comfortably in retirement :
Significance level :
Critical value :
The confidence interval for population proportion is given by :-
Hence, the 90% confidence interval for the proportion of adults who are worried about having enough money to live comfortably in retirement = (0.504, 0.556)
X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:
y=x-3
(x+5) / (y+5)=5/6
we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20
y=x-3=-20-3=-23
Teh sum of the numerator an denominator=-20+(-23)=-43
Answer: -43
The marginal propensity to consume is the proportion of an increase in income that is spent by the economic agent on consumption
<h3>What is MPC?</h3>
It should be noted that the marginal propensity to consume is the proportion of an aggregate raise in pay which a consumer spends on the consumption of goods and services.
It's a component of the Keynesian macroeconomic theory. It is calculated as the chnae in consumption over the change in income.
For example, let's say that the consumption increases by 70 cents for every additional dollar of income. This will be:
= 0.7/1
= 0.7
