What formula does proc surveymeans use to conduct the t-test?

Hi,

I'm trying to figure out the formula that proc surveymeans uses when conducting a test on two independent sample with replicate weights.

The following is the code that generated a t-score on my dataset, but I do not know what formula proc surveymeans used to arrive at the t-value:

proc surveymeans data = test_19
varmethod = jackknife alpha = 0.1 mean var stderr sum
    ;

   var flag1;
    weight bw0;
    repweights bw1 -bw80 / JKCOEFS = 0.05;

    domain treatment/diffmeans adjust=bon;

    ods output Statistics=MyStat_c;
run;

The dataset is structured as:

Treatment Flag1

T 1

T 0

T 1

C 0

C 1

Thank you!
