The Central Limit Theorem states that, for any distribution, as n gets larger, the sampling distribution:() A. becomes larger. B. becomes smaller. C. approaches a normal distribution. 相关知识点: 试题来源: 解析 C As n gets larger, the variance of the distribution of sample means is re...
The Central Limit Theorem For simple random samples from any population with finite mean and variance, as n becomes increasingly large, the sampling distribution of the sample means is approximately normally distributed. The Central Limit Theorem The Central Limit Theorem states that under ...
The central limit theorem states that any set of variates with a distribution having a finite mean and variance tends to the normal distribution. This allows statisticians to approximate sets of data with unknown distributions as being normal. ...
The central limit theorem states that for a large enoughn, X-bar can be approximated by a normal distribution with mean µ and standard deviation σ/√n. The population mean for a six-sided die is (1+2+3+4+5+6)/6 = 3.5 and the population standard deviation is 1.708. Thus, if ...

67.The Central Limit Theorem states that as the sample size gets larger enough, the sampling distribution of the mean is approximately normally distributed. This is true regardless of the shape of the distribution of the individual values in the population. ...
The central limit theorem (for sums) states that even if a population distribution is non-normal or the shape is unknown, the shape of the sampling distribution of the sample sums will be approximately normal if the sample size is large enough. The mean of the sampling distribution of...
What does the Central Limit Theorem state? a ) The larger the sample size, the more accurate the estimate. b ) The mean of the sample is equal to the mean of the population. c ) The distribution of sample means approaches a no...
tinuity theorem states that the distribution of the limit of random variables is uniquely defined by the limit of the corresponding characteristic functions. So all we have to do is understand the limit of the characteristic functions of our summed random variables. We will see that the charac...
