CHISQ.INV.RT Returns the inverse of the right-tailed probability of the chi-squared distribution.
If probability = CHISQ.DIST.RT(x,…), then CHISQ.INV.RT(probability,…) = x. Use this function to compare observed results with expected ones in order to decide whether your original hypothesis is valid.
Syntax

Parameters
Probability – A probability associated with the chi-squared distribution.
Deg_freedom – The number of degrees of freedom.
Return Value
Returns the inverse of the right-tailed probability of the chi-squared distribution.
