Test on Two Mean Vectors

Hello. I am currently taking a multivariate statistics course and having trouble with this problem.

Test Ho: μ' =(6,11)

....... 3 10
Y = (6 12)
...... 5 14
...... 10 9

I know I need to find the combined T^2 but am not really sure where to start or what steps to take. Thank you. I heard back from my teacher and I know I have to use SAS now
