Let z be a standard normal random variable. Determine the value c of such that p(z \le c) = .8869.Let Z be a standard normal random variable, i.e., the probability distribution of Z is normal with mean 0 and variance...
suppose that Z represent a standard( tabled) normal random variable.find the P(Z2.25) 相关知识点: 试题来源: 解析 由题意,随机变量Z服从标准正态分布, 因此P(Z<-2.25 or Z>2.25)=1-P(-2.25 一般地,计算此概率,需查标准正态分布表,查得P(Z<2.25)=0.9878; 于是P(Z<-2.25 or Z>2.25)=2[1...

There is a related question on thesquare of a standard normal variable, but it assumes a zero mean and I can't figure out how to generalise the answer to the non-zero mean case. Then there is a very related question onthe variance of powersof a random variable, but it's about the ...
