Independent random samples selected. One has 15 points, one has 16.
It asks "is there evidence μ2 - μ1 > 10? Test at 0.01 level of significance.
2. The attempt at a solution
There are 29 degrees of freedom. The t-score at 0.01 for 29 is 2.462.
I just don't get how I test whether

1) Do I just find the t-score, find μ2 - μ1, and see how many standard deviations it takes to get 10, and i.e. if it takes over 3, say very little probablity etc?
