Estimated mean Hemoglobin (I-lb) of 100 women is 10g%. Standard detion (a) is lgm%. Standard error of estimate will be -

Ans. is 'd' i.e., 0.1 o Standard error of mean is calculated as Standard Detion/ VT1; where 'n' is the total number of values within the sample. Thus the standard error of mean hemoglobin from the above sample would be (1.0/ Vioo ) or 1/10 or 0.1.
