【单选题】某小麦品种在田间出现变异植株的概率为0.0045,今调查100株,恰好有2株出现变异的概率用SAS命令计算语句正确的是:【 】
A. probbnml(0.0045,100,2); B. 1- probbnml(0.0045,100,2); C. cdf("BINOMIAL",2,0.0045,100); D. cdf("BINOMIAL",2,0.0045,100)-cdf("BINOMIAL",1,0.0045,100);
A. probbnml(0.0045,100,2); B. 1- probbnml(0.0045,100,2); C. cdf("BINOMIAL",2,0.0045,100); D. cdf("BINOMIAL",2,0.0045,100)-cdf("BINOMIAL",1,0.0045,100);
举一反三
- 如图1所示OC=60.500 m , β=(∠AOC0)-β1(∠AOC)=+3”,则CC0的值为( ) A: +0.009m B: - 0.009m C: 0.0045 m D: + 0.0045 m
- 假设一张考卷有10道选择题,每道题有4个选择答案,其中只有一个是正确的。某考生靠猜测,则至少能答对6题的概率用SAS命令计算语句正确的是:【】 A: probbnml(0.25,10,6); B: 1-probbnml(0.25,10,6); C: cdf("BINOMIAL",6,0.25,10); D: 1-cdf("BINOMIAL",5,0.25,10);
- 假设一张考卷有10道选择题,每道题有4个选择答案,其中只有一个是正确的。某考生靠猜测,则恰好答对6题的概率用SAS命令计算语句正确的是:【】 A: probbnml(0.25,10,6); B: 1-probbnml(0.25,10,6); C: PMF("BINOMIAL",6,0.25,10); D: 1-cdf("BINOMIAL",5,0.25,10);
- 下列数据为两位有效数字的是( ) A: 0.0045 B: 0.00545 C: 0.3421 D: 0.1145
- 红外线的波长范围为()。 A: 0.40~0.0045μm B: 0.40~0.76μm C: 0.76~1000μm D: 1~300mm
