Yes it looks like a really good student exercise into the sampling properties of a distribution.
What you need to do is initialize vectors beforehand that will contain the mean and variance values. Then simply use a for() loop that generates 5 random numbers. Use the mean(), var() and store the values into the vector. Then a simple plot() should suffice. Since it is a simple problem, I will leave you to it. -----Original Message----- From: Murray Jorgensen [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 19, 2003 12:39 PM Cc: [EMAIL PROTECTED] Subject: Re: [R] r-help using random generating Student Exercise?!
