If Z is a standard normal random variable, and Pr(Z > c) = 0.75, then find the value of c to 4 decimal place.相关知识点: 试题来源: 解析 -0.6745 标准正态分布中,Pr(Z > c) = 0.75意味着Z的左侧累积概率为Pr(Z ≤ c) = 1 - 0.75 = 0.25。通过查找标准正态分布表或使用反函数计算,...
Let Z be a standard normal random variable, find P(-1.23 less than Z less than 1.15).Given that z is a standard normal random variable, what is the probability that -2.51 less than or equal to z less than or equal to ...
Standard Normal Distribution is a random variable that is calculated by subtracting the mean of the distribution from the value being standardized and then dividing the difference by the standard deviation of the distribution. The Formula of Standard Normal Distribution is shown below: Z = (X –μ...
The NORM.S.DIST Function[1]is categorized under ExcelStatistical functions. It will calculate the Standard Normal Distribution function for a given value. The NORM.S.DIST function can be used to determine the probability that a random variable that is standard normally distributed would be less th...
If z is a standard normal random variable, find a {eq}z_0 {/eq} such that {eq}P(z < z_0) = 0.8869 {/eq}. (Round your answer to two decimal places.) Z-Value In statistics, the z-value is the value obtained from the standar...
