| Abstract | ||
| Aim of this research is to use panel of arithmetic mean and the standard deviation and so on their importance in the practical aspect of the production process and to know its relevance to the practical study and efficiency of these panels in terms of the practical application of scientific productivity is it under control or not?For this purpose, we were taken the data from a Masafy Company in Duhok governorate to know the percentage of calcium in mineral water which the number of observations was (140) observations and was divided into (28) samples and each sample contained (5) observations. From the result, the panel of the standard deviation is look like normal for the production process which each points under the control limit for the amount of the percent of calcium, this means the possibility of using this panel in the future to control the percent of substance of calcium, and the panel of medium is outside the control limits of the proportion of calcium, which means the production process Image is not normal Distilled water | ||
