Thanks for the quick reply. We've done a few similar examples, but like most of our homework, none of the questions match the practice problems.

The time it takes to complete a project is a random variable Y with the exponential distribution with parameter β=2 hours. Apply the central limit theorem to obtain an approximation for the probability that the average project completion time of a sample of n=64 projects undertaken...

Evaluate the limit if it exists or show it does not exist. limit as (x,y) approaches (0,0) (2x^2y)/(x^2+2y^2)Had this problem on a test and got points taken off - I'm trying to figure out what I did wrong. Obviously when we plug in (0,0) we get 0/0 which isn't allowed. I let x=y and ended up...
