The standard deviation of GPAs (grade point averages) of all male students at a college is .35 and the standard deviation of GPAs of all female students at the same college is .34. Suppose we take one sample of 40 male students and another sample of 50 female students from this college. What is the standard deviation of the sampling distribution of the difference between the mean GPAs of these two samples?
