Margin of error with c s n
The margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a census of the entire population. The margin of error will be positive whenever a population is incompletely sampled and the outcome measure has positive variance, which i… Web橦华轻奢潮流童装女童网红洋气套装夏季儿童中大童夏装时髦两件套CSN 黑白套装 120cm图片、价格、品牌样样齐全！【京东正品行货，全国配送，心动不如行动，立即购买享受更多优惠哦！
