Population XX has a standard deviation σX=8\(\sigma\)_X = 8, and population YY has a standard deviation σY=12\(\sigma\)_Y = 12. How many times larger than Population XX's sample size does Population YY's sample size need to be to achieve the same margin of error for the mean?

Population $X$ has a standard deviation $sigma sub X equals 8$ , and population $Y$ has a standard deviation $sigma sub Y equals 12$ . How many times larger than Population $X$ 's sample size does Population $Y$ 's sample size need to be to achieve the same margin of error for the mean?
