QUANTS sampling

Postby danish.hassan7 » Mon Jun 12, 2017 9:28 am

Q. Sample size is 35, population S.D is 3%, sample S.D is 2.5%. SEM is 0.5071.

DOUBT: Now does it mean that the SEM is the approx error of population S.D and sample S.D????

If yes then I am confused that SEM is the S.D of means of samples. How??

SEM is 0.4226 which is arrived by dividing standard deviation of the sample by sqrt(number of samples). Definition of SEM as stated by yourself is correct.
