An attempt has been made to estimate reliability for mean of normal population with known CV. The function is derived and curves have shown this function. It seen that effect skewness considerable but the kurtosis not much.

The coefficient of variation is widely used as a measure data precision. Confidence intervals for single when the follow normal distribution that symmetrical and difference between coefficients two populations are considered in this paper. First, confidence obtained with adjusted generalized interval (adjusted GCI), computational, Bayesian, Bayesian approaches. These approaches compared existin...
