I can’t tell what’s being done in that calculation.
I’m getting a p-value of 0.108 from a Pearson chi-square test (with cell values 55, 809; 78, 856). A chi-square test and a two-tailed t-test should give very similar results with these data, so I agree with Michael that it looks like your p=0.053 comes from a one-tailed test.

Yes, you’re right. Sorry! I redid it computationally and also got 0.108. Post updated.
