Hello,
I have the mean and the variance for a Chi squared distribution.
I want to create this Chi squared distribution using the mean and the variance that I have, can I ?
Thank you.

If you want to approximate your x with the variance of 0.01 via chi^2, then it is quite impossible--the variance of chi^2 must be integer. If you want to construct the new chi^2 variable based on your x implying it is normally distributed - see my earlier comment.
