normality uses

When can the normal distribution be used as an approximation to the binomial distribution? => n . p = 5, n . q = 5 or n . p ≤ 5, n . q ≤ 5 or n . p > 5, n . q < 5 or n . p ≥ 5, n . q ≥ 5..

Normality Equation - To calculate the volume of a definite solution required to prepare solutions of other normality, the following equation is used: N 1 V 1 =N 2 V 2 , where N 1 =initial normality and N 2 =normality of the new solution, a nd V 1 = ..

ECG is a graphic display or recording of the electrical variations produced by heart muscle during a cardiac cycle. The activity of the heart create an electrical field which is conducted through the surrounding body tissues to the surface of the body. Two electrodes are placed on the surface of th..
