You are interested in estimating the mean of a population. You plan to take a random sample from the population and use the samp
Alja [10]

Answer: The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.

You can assume that the sampling distribution of M is normally distributed for any sample size.

Step-by-step explanation:

  • According to the central limit theorem , if we have a population with mean (\mu) and standard deviation \sigma , then if we take a sufficiently large random samples from the population with replacement ,  the distribution of the sample means will be approximately normally distributed.
  • When population is normally distributed , then the mean of the sampling distribution = Population mean (\mu)
  • Standard deviation of the sampling distribution = \dfrac{\sigma}{\sqrt{n}} , where \sigma =  standard deviation of the population  , n=  sample size.

So, the correct statements are:

  1. You can assume that the sampling distribution of M is normally distributed for any sample size.
  2. The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.
