1. What is the mean and variance of the sampling distribution of the
sample means?​


Sagot :

Answer:

the population variance divided by N, the sample size

Step-by-step explanation:

Answer:

That is, the variance of the sampling distribution of the mean is the population variance divided by N, the sample size (the number of scores used to compute a mean). Thus, the larger the sample size, the smaller the variance of the sampling distribution of the mean. ... The variance of the sum would be σ2 + σ2 + σ2.
