Answer:
The conditions for creating a confidence interval for the population proportion have been met.
Explanation:
There are the following conditions to build a confidence interval for a population proportion:
Sample of size n from a large population
Individuals chosen independent of one another
At least 15 failures and 15 sucesses in the sample.
In this problem, we have that:
Sample of 100 people
They are chosen at random at the market, so it means that the probability that an individual likes the new design is independent of any other individuals.
82 successes and 18 failures.
So yes, the conditions for creating a confidence interval for the population proportion have been met.
The correct answer is B.) The problem of scarcity does not exist.
Because since it is a 'perfectly competitive' market then scarcity shouldnt exist.

Answer:
Market value of stock A = 20 shares x $10 = $200
Market value of stock B = 15 shares x $3 = $45
Market value of stock C = 10 shares x $5 = $50
Total market value $295
Amount to invest in stock A
= $200/$295 x $5,000
= $3,389.83
Explanation:
In this case, we will calculate the market value of each stock by multiplying the number of each stock by their corresponding market prices.
Thereafter, we will divide the market value of stock A by the total market value multiplied by amount available for investment ($5,000).
Answer:
The actual unemployment rate was higher during the recession of 1990−1991, while cyclical unemployment was higher in 2001.
Explanation:
Given data in the question
In the year 1990-1991
The natural rate of unemployment = 5.9%
The rate of the actual unemployment = 7.0%
In the year 2001
The natural rate of unemployment = 4.8%
The actual unemployment rate = 6.0%
As we can see that
The actual unemployment is high in the year 1990-1991 i.e 7.0% as compare to the year 2001 i.e 6.0%
While the cyclical unemployment rate is high in 2001 i.e 1.2% (6.0 - 4.8%) as compare to the year 1990-1191 i.e 1.1% (7.0% - 5.9%)
Answer:
8.09%
Explanation:
Year Inflation rate 1 + Inflation rate
1 0.03 1.03
2 0.04 1.04
3 x 1+x
Average rate 0.05 0.05
1 + Average rate = [(1+r1)*(1+r2)*(1+r3)]^(1/3)
1.05 = [1.03*1.04*(1*x)]^(1/3)
[1.0712*(1+x)] = (1.05)^3
[1.0712*(1+x)] = 1.157625
1 + x = 1.157625 / 1.0712
1 + x = 1.080681
x = 1.080681 - 1
x = 0.080681
x = 8.09%
Thus, the periodic Inflation rate in year 3 is 8.09%
