Answer:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative.
This means that 
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Answer:
y=-1x+-3
Step-by-step explanation:
You could change 0.393 to a fraction by putting it over 1000
in this case put it over 0.393= 396/1000
the / is the fraction
it is 396 over 1000
Answer:
1.5%
Step-by-step explanation:
According to the Taylor rule, the federal funds rate targeted by the Fed is:
Where AI is the actual inflation (1%), DI is the desired inflation (2%) and PD is the deviation from potential (2%):
The Fed should target a federal funds rate of 1.5%.
(33)(1/9•2-6+2)
18-6+2=14
33•1/14 = 33/14
The answer is 33/14 or 2.35714
