Question

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?

Answer 1

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
