Can you explain how we got this formula for CI?
Can you explain how we got this formula for CI, specifically why did we put the standard deviation as standard error in the formula. Isn’t standard error equal to S.D./Sqrt(n)?

Standard errors are the "standard deviations" of sample statistics.
Kindly refer to the table below for standard errors.
