Scientific research, industrial and agricultural manufacturing, and management work are inseparable from data, and the organization, analysis, and interpretation of these data are inseparable from statistical methods. Statistics is a discipline that studies the organization, analysis, and correct interpretation of digital data. People obtain various digital data from different sources. These digital data are usually disorganized and must be sorted and simplified before they can be used. Using perfect statistical methods, data can be sorted and arranged in an orderly manner. Using graphics or a few important parameters, the characteristics of a large amount of data can be expressed. This can avoid incorrect interpretations and reduce the cost of obtaining satisfactory data to a minimum, thereby improving economic benefits. The national standard "Statistical Processing and Interpretation of Data" includes the following items: Determination of statistical error range (GB/T3359) Estimation and confidence interval of the mean (GB/T3360) Comparison of two means in the case of paired observations (GB/T33G1) Estimation and test of a distribution parameter (GB/T 4088) Estimation and test of Poisson distribution parameters (GB/T4089) Normality test (GB/T4882)

The confidence interval used in this standard satisfies the following conditions: the frequency of the event that the obtained confidence interval contains the true input value is approximately equal to the confidence level 1--α. Specifically, the two-sided interval should satisfy: P(>,<)<,1-α The one-sided confidence interval should satisfy:
