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...
-1.2 of the table with the column holding 0.01. the table explains that the probability that a standard normal random variable will be less than -1.21 is 0.1131; that is, p(z < -1.21) = 0.1131. this table is also called a z-score table . z 0.00 0.01 0.02 0.03 0.04 0.05 -3.0 ...

If z is a standard normal random variable, find z given that the area to the right of z is 0.1.Given that z is a standard normal random variable, find z given that the area to the right of z is 0.3300.If z is a standard normal random variable, ...
Let z be a random variable with a standard normal distribution. Find {eq}P(-2.9 < z < 0.4) {/eq}. The Standard Normal Distribution: The standard form of the normal distribution, called the standard normal distribution (SNV), is rather more used than the Normal ...
to -1.21, we will check the cross-reference the row that contains -1.2 of the table along with the column that holds 0.01. We will find that a standard normal random variable will be less than -1.21 is 0.1131. this means that P ( z ) = 0.1131 which is the z score of the table....
This table contains values of the cumulative distribution function for the standard normal random variable \\(\\Phi (z) = P(Z \\le z) = \\int\\limits_{ -\\infty }^z {{1 \\over {\\sqrt {2\\pi } }}{e^{ -{x^2}/2}}dz.} \\)...
A z score table or a standard normal table as it is also referred to is, as we already mentioned above, one very effective way that researchers and statisticians use to determine the probability or area that corresponds to a specific z score. But how can you determine it and put it into...
Z represents standardize random variables along with all the profanities which are associated with the ranges of values of Z, which are given in the distribution table. As per the formula, any random variable is standardized by deducting the mean of the distribution from the value being standardiz...
normal distribution n (Statistics)statisticsa continuous distribution of a random variable with its mean, median, and mode equal, the probability density function of which is given by (exp-[(x–μ)2/2σ2]/σ√(2π)) where μ is the mean and σ2the variance. Also called:Gaussian distribu...
