Answer:
b) the standard deviation of the sampling distribution of the mean
Explanation:
Typically, the standard error of the mean is a term in statistics that describes the deviation in the sample mean from the actual mean of a population.
Therefore, in this case, the standard error of the mean is "the standard deviation of the sampling distribution of the mean."
(x+y)^2=56
x^2+2xy+y^2=56. we know that xy=12
so 2(xy)=24
x^2+24+y^2=56
x^2+y^2=56-24
x^2+y^2=32. <-------------
