Here,zis a random complex variable whose real and imaginary parts are independent normally distributed random variables with mean 0 and variance 1/2. The underlying number generator forrandnis a pseudorandom number generator, which creates a deterministic sequence of numbers that appear random. These...

The lead-time demand is also taken to be a normally distributed continuous fuzzy random variable by connecting it to the annual demand through the length of the constant lead-time. Under these assumptions, a methodology is proposed to minimize the crisp equivalent of the expected total annual ...

Consider a normally distributed random variable x with a mean of 20 and a standard deviation of 30. Compute P(x>80). Normal Distribution:If the distribution of a population and its sample means is normal, the mean of both distributions i...
mean是平均数，是一组数据的总数量除以这组数据的总份数所得的商，standard deviation是标准差，是各个数据与平均数之差的平方的平均数的算术平方根。inter-quartile range 是四分位差，它是上四分位数（QL）与下四分位数（QU）之差。这道题目应该是选择A，希望我能帮助你解疑释惑。A...
