Hello, I would like to ask for a question regarding calculation of the unbiased estimate of variance of x based on the given information:
Σ(x+10)=12290 and Σ(x+10)²=811212
given sample size n=200
So far I just knew about how to solve the unbiased estima of mean of x which is 51.45, but I'm not sure about how to find out the unbiased estimate of variance of x. Thanks and appreciate for the help in advance.
