"Let N be the number of earthquakes occurring somewhere in the world in a 1-year period"
a) I have decided that this fits a poisson distribution. Is this correct? because they haven't given a mean value?
b) what are the set of values this random variable can take? So the support of the distribution of the random variable. Isn't this just 0 - infinity? how do I write this as an answer?
See whether the Central Limit Theorem can be used to a good effect. Also, check up the following link: http://www-stat.wharton.upenn.edu/~dsmall/stat510-f05/lectures/notes11.doc
