 Posted: Fri Nov 06, 2009 10:03 am Post subject: Hypothesis Testing involving Poisson Distribution |
 |
|
Hi, Could anybody help me solving it? I am sure how to do a hypothesis test of Poisson distribution with small sample.
A person will decide to have her telephone disconnected if her
average number of calls per day is lsess than 2. On five randomly selected days,
her recorded number of calls were 0, 2, 1, 1, 1.
a) Briefly state why the Poisson(λ) assumption is suitable as a probability
distribution for the number of calls.
b) At the 5% level of significance, and based on information from this random
sample, discuss whether she should decide to disconnect her phone.
Any help would be much appreciated!
Thanks! |
