You cannot find the exact mean and variance from a sample you can only give a range in which you think they lie. Read up on Confidence Intervals.
Hello,
I'm trying to understand how to find Population Mean and Variance from Sample mean and Variance assuming a Normal Distribution.
I was given a sample where I calculated the sample mean and variance. It then asks to estimate the mean and variance assuming that the values are Gaussian Distributed.
Thanks for any help,
Jeff
