·
·<img src="https://u.qsxt.info/degree/school_4595/39538220_20240114114938447_382.jpg"下列关于中心极限定理的说法中,正确的是( )。
·它揭示了在一定条件下大量随机变量的平均值近似服从正态分布的规律
·它适用于任何分布的数据
·它说明当样本量足够大时,样本均值的分布近似服从正态分布
·它指出,只要样本量足够大,无论总体分布如何,样本均值的分布总是近似服从正态分布
下列关于点估计的说法中,正确的是( )。
·点估计是用样本统计量来估计总体参数的方法
·点估计的结果是一个具体的数值,而不是一个区间
·点估计的精度可以用置信区间来衡量
·点估计是无偏估计的充分必要条件是估计量的期望等于被估计的总体参数
下列关于假设检验的说法中,正确的是( )。
·假设检验的基本思想是小概率事件在一次试验中几乎不可能发生
·在假设检验中,原假设和备择假设的地位是相同的,可以随意设定
·显著性水平α是指在原假设为真时拒绝原假设的概率
·如果检验统计量的观测值落在拒绝域内,则拒绝原假设,否则接受原假设
下列关于回归分析的说法中,正确的是( )。
·回归分析是研究自变量和因变量之间关系的一种方法
·简单线性回归模型是指一个自变量和一个因变量之间的线性关系模型
·相关分析是研究变量之间是否存在某种关联的一种方法,但它不能指明变量之间关系的具体形式
·在多元线性回归模型中,各自变量对因变量的影响是相互独立的,一个自变量的变化不会引起其他自变量的变化。
