摘要
本文通过分析确认了居民燃气消耗量的随机性,进而证明其为服从正态分布的随机变量。叙述了确定居民燃气消耗定额的置信区间及在不同精度要求下,于样容量的最低取值标准的统计学方法。
The paper affirms the stochastic properties of household gas consumption, and then proves a random variable in normal distribution. Accordingly, a statistic method for calculation of probability interval for household gas consumption quota, and of the lowest value criterion for the sampling volume under various precision requirements is proposed.
