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.
They most likely drop the prices
Answer:
a. Short futures
b. $37,500
Explanation:
Since the price of the future coffee would be lower than the future prices so it would reflect the short futures, not the long futures
And, the impact would be
= Number of coffee pounds × number of contract position × coffee price per pound in cents
= 37,500 pounds × 10 × 0.10
= $3,7500
We simply multiply the coffee pounds, contract position and per pounds in cents so that the accurate value can come.
The answer is A. "lack" is a negative word and it is the only drawback.
