No, 94 people total got infected. At least 85 were in the control group.

Those are the numbers that matter, statistically. If the total number of people in the study were 2 thousand or 2 billion doesn't enter into the math.

That's not true, population size absolutely 'enters into the math'. 9 vs. 85 does not give the same result independently of whether N=94, 200, 2k, or 2B.

It affects confidence, and potentially the result of the test entirely. I won't be more specific because stats was never a strong suit and my memory's hazy, but I remember enough to know it matters!
