13、；（）7. 在进行成组设计资料的t 检验中, h0： 1=2, h1 ： 1 2 , =0.05 ；如检验的结果为p=0.065,就结论为两总体均数相等；（）8. 进行多元线性回来时, 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 值为单侧检验的 10医学统计学的全部内容就为对收集来的数据进行统计分析；2 倍；（）11. 在直线回来分析中, 要求因变量听从正态分布；（）12. 在进行三组均数的方差分析中,如检验的结果为p=0.015,就结论为三个总体均数都不相等；（）13. 进行多元线性回来时,如偏回来系数b1>b2,就指标 x1 对 y 的作用大于 x2

14、 对 y的作用（）14. 假如理论上 a 药的确有减肥作用,但在一次临床试验中,它的降低体重值和劝慰剂的差异无统计学意义,可能为样本量太小；（）15. 如 x1 和 y 之间的简洁相关系数有统计学意义,就在多元逐步回来中,x1 肯定会被选入方程；（）16. 如 x1 和 y 之间的简洁相关系数无统计学意义,就在多元逐步回来中,x1 肯定不会被选入方程；（）17. 二个率进行比较的显著性检验中,用准确概率运算为最正确的；（）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. 回来分析中,回来系数越大,回来系数的标准误也越大

15、；（）20. 正态分布的均数不肯定比标准差大；（）二.填充题play levels ca dres in enterpri se devel opme nt in the of back bone backbone role; t o full strengtheni ng members youth w ork、 full play yo uth em ployees i n company development in t he of force role; to impr ove indepe ndent commission against corr upti on w ork lev
