## Chi-Square Distribution Confidence Interval for Variance

Basically, chi-square (with one degree of freedom) variable is the square of a standard normal variable and chi-square distribution has additive property (sum of two independent chi-square distributions is also a chi-square variable). letвђ™s discuss the different uses of chi-square distribution in the testing of hypothesis in real life situations..
