老师,您好!在直接法计算CFO时,“四支”中支付给供应商的钱,严格一点来讲要不要考虑prepaid expenses,即-cash paid to suppliers=-COGS+ΔA/P+depreciation included in COGS-Δinventory-Δprepaid expenses?
已回答听晕了 X拔到底定义的是什么哦, 抽样样本的平均值吗?比如100个X,n=50,就是说100个数里面抽取了50个数字。 然后这样的抽样过程一致反复,挑选了若干个50个数字的样本。 每个样本去计算一下平均值为X1 X2 X3 。。。。然后这些X1 X2 X3再去算平均值就是X拔吗?
已回答This process is used to estimate the population mean and standard deviation, which usually are unknown. 这题答案里的这句话是不是有错?老师说符合中心极限定理的条件是 known mean and known standard deviation.
