随机正常分布

Question

我有一个csv文件，看起来像：

subjects,       WeightedAverage,     WeightedStandardDev,    NumberofExams,
MathMark,              1.5,                 0.2,                   5,
PhysicMark,            1.6,                 0.4,                  10,
EnglishMark,            3,                  1.2,                  8,
PhiloMark,             8.2,                 1.5,                  9,
Others                 9.2,                 3.2,                  5,   

我有另一个文件，我需要为上面的每个主题以这种方式生成数据：

例如，对于主题MathMark，相应的表应为：

 NumberofExams                                     Mark                                                                              1                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
2                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
3                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
4                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
5                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)

例如对于主题EnglishMark，相应的表应该是：

NumberofExams                                   Mark                                                                                            
1                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                                2                           =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                              3                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                               
4                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                  
5                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)             
6                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)   
7                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)
8                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)

想要生成NumberofExams正态分布的随机数（WeightedAverage，WeightedStandardDev）。如何从另一个csv文件中获取这些信息并计算Excel中所需的随机数。任何公式或宏都表示赞赏。
