Question

Use the formula to find the standard error of the distribution of differences in sample means x̅ 1-x̅2. Samples of size 120 from population 1 with mean 91 and standard deviation 13 and sample size 90 from population 2 with mean 79 and standard deviation 18.                                                                                                                                                                                                                                                          
ROUND YOUR ANSWER FOR THE STANDARD ERROR TO TWO DECIMAL PLACES.                                                                                       
STANDARD ERROR =  ?
