Answer:
The probability of pet dogs adopted between 15% and 20% is 0.4096.
Explanation:
Let <em>X</em> = number of pet dogs adopted from an animal shelter.
The proportion of pet dogs adopted from an animal shelter is, <em>p</em> = 0.19.
The sample of pet dogs selected is of size, <em>n</em> = 80.
A Normal approximation to Binomial can be applied in this case since,
- np = 80 × 0.19 = 15.2 > 10
- n(1 - p) = 80 × (1 - 0.19) = 64.8 > 10
So the sample proportion (
) of pet dogs adopted from an animal shelter follows a normal distribution.
Mean of is:
Standard deviation of is:
Compute the probability of between 15% and 20% as follows:
Thus, the probability of pet dogs adopted between 15% and 20% is 0.4096.
Answer: $19963.6
Explanation:
The present value of this investment if the interest rate is 8% would be gotten by using the formula below;
PV = PMT/[r × (1+r)^n / (1+r)^n -1]
PV = 5000[8% × (1+8%)^5 / (1+8%)^5-1
PV = 5000[0.08 + 1.08^5 / 1.08^4
PV = 19963.6
Therefore, the present value of the investment is 19963.6
<span>The price level would be lower than would otherwise have occurred.
Since the economy is a inflation gap </span><span>input prices will eventually increase in the
absence of any fiscal policy, causing the price level to rise and output to fall back to potential
output. The contractionary fiscal policy will reduce aggregate demand and lower output to
potential output while at the same time lowering the price level. Thus the only difference
<span>between the two is a lower price level with the contractionary fiscal policy.</span></span>
Answer:
The answer is :
B) data about the economy from the past.
