Question 1.
In a Binomial distribution, what parameters define the model?
Show hintHide hint
Think about what characterizes a Binomial experiment.
Question 2.
What does the λ (lambda) represent in the Poisson distribution?
Show hintHide hint
This is a rate parameter.
3Question 3.
What is the condition necessary for the Binomial distribution to approach the Poisson distribution?
- n becomes finite
- n approaches infinity and p approaches zero
- p becomes 1
Show hintHide hint
Consider 'infinity' as a keyword.
4Question 4.
True or False: The mean and variance of the Poisson distribution are both equal to λ.
- True
- False
Show hintHide hint
Recall the properties of the Poisson distribution.
Question 5.
A renewable energy facility produces, on average, 20 power outages per month. Calculate the probability of having exactly 5 outages next month. Use λ=20.
Show hintHide hint
Convert the values into the Poisson formula carefully.
Question 6.
Discuss how you would use the Poisson distribution to model the call volume in a call center with an average of 10 calls per hour. What assumptions must be kept in mind?
Show hintHide hint
Think about independence and rate stability.
