The mean and standard deviation of a population being sampled are 64 and 6, respectively. If the sample size is 50, what is the standard error of the mean?

how do I find the standard error?

SEM - Standard error of the mean;

You can find the standard error with a formula:

SEM = s / √n, where s is the standard deviation and n is the sample size;

SEM = 6 / √50 = 6 / 7.071

Answer:

SEM = 0.8485
