17、的显著性检验结果和回归系数 b 的显著性检验结果完全一致。（）6. 从总体中抽出一部分个体就构成一个样本。（）7. 在进行成组设计资料的t 检验中， H0：1=2，H1：12，=0.05。若检验的结果为 P=0.065，则结论为两总体均数相等。（）8. 进行多元线性回归时， 进入方程的自变量越多越好。（）9. 同一组资料作团体 t 检验， 双侧检验的 P值是单侧检验的 2 倍。（）10 医学统计学的全部内容就是对收集来的数据进行统计分析。（）11. 在直线回归分析中，要求因变量服从正态分布。（）12. 在进行三组均数的方差分析中，若检验的结果为P=0.015，则结论为三个总体均数都不相等。（）

18、13. 进行多元线性回归时，如偏回归系数b1b2，则指标 X1对 Y的作用大于 X2 对 Y的作用（）14. 如果理论上 A药确实有减肥作用，但在一次临床试验中，它的降低体重值和安慰剂的差异无统计学意义，可能是样本量太小。（）15. 如 X1和 Y之间的简单相关系数有统计学意义，则在多元逐步回归中，X1一定会被选入方程。（）16. 如 X1和 Y之间的简单相关系数无统计学意义，则在多元逐步回归中，X1一定不会被选入方程。（）17. 二个率进行比较的显著性检验中，用确切概率计算是最正确的。（）18. 如显著性检验的结论为A组均数大于 B组，P0.0021，这时 P表示该结论犯错误的可能性的大小。

19、（）19. 回归分析中，回归系数越大，回归系数的标准误也越大。（）20. 正态分布的均数不一定比标准差大。（）二、填充题名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - - - - - - 第 1 页，共 5 页 - - - - - - - - - We will continue to improve the companys internal control system, and steady improvement in ability to manage and control,
