Use the formula to find the standard error of the distribution of differences in sample means, X1 - X2 . Samples of size 100 from Population 1 with mean 92 and standard deviation 11 and samples of size 70 from Population 2 with mean 70 and standard deviation 15.
Round your answer for the standard error to two decimal places. standard error =
solution:-
given that n1 = 100 , x1 = 92 , s1 = 11
n2 = 70 , x2 = 70 , s2 = 15
standard error formula
=> sqrt((s1^2/n1)+(s2^2/n2))
=> sqrt((11^2/100)+(15^2/70))
=> sqrt(1.21+3.21)
Standard Error = 2.10
