A population has a standard deviation of 5.5. What is the standard error of the sampling distribution if the sample size is 81?

And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution and for this case we know that the distribution is given by:

And the standard error would be:

And replacing we got:

Step-by-step explanation:

For this case we know the population deviation given by:

And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution and for this case we know that the distribution is given by:

And the standard error would be:

And replacing we got:

answer: (1,3) (3,-1) (5,-5) ?
