I want write a short block of computer code that allows me to generate a random gassuian number. For example, if the inputs are mean = 100 and sd = 10, if I generage 1000 random numbers, I'd like 67% of them to be between 90 and 110, 98% of them to be be between 80 and 120. But I only know how to generate random numbers between 2 different values. For example I can generate random numbers between 90 and 110, but 90 would have just as as much probability of being generated as 100. How can I generate numbers that would make a nice bell curve if I generated enough of them? Thanks.
