The following results were reported on the number of heterosexual partners individuals had had over the previous five year period.

Men:Sample Size, n = 4620 Mean = 3.8 Standard Deviation = 6.7
Standard Error = 0.098

Women:Sample Size, n = 6228 Mean = 2.4 Standard Dev. = 4.6
Standard Error = 0.058


What is the standard error of Y in men? What is it in women? Assume that the sampling was random?
