Homework Answers
False.
The mean of sampling distribution of x-bar is always equal to the mean of sampled population. The sampling distribution of sample mean is nothing but probability distribution developed from repeatedly taking samples of size n and finding means for each samples. These combined results form probability distribution. So the sample mean of x-bar is always equal to the mean of sampled population.

Which of the following statements about the sampling distribution of the sample mean, x-bar, is not true? The distribution is normal regardless of the shape of the population distribution, as long as the sample size,n, is large enough. The distribution is normal regardless of the sample size, as long as the population distribution is normal. The distribution's mean is the same as the population mean. The distribution's standard deviation is smaller than the population standard deviation. All of the above...

1. Generating the sampling distribution of the mean Аа Аа Suppose you use sampling techniques to estimate the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8. To do this, you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample The true mean (u) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is and...

Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.
