My main questions are:

I have a problem with a box labeling some numbers like so:

n1 = 81

n2 = 80

y1 (with a line above it) = 41

y2 (with a line above it) = 54

s1 = 21

s2 = 19

I can figure out the whole extended problem to get a t-value, which is -4.12 (rounded), and there are df = 157.80

The next step says the formula I want to use is 2*P(t157.80 (less than symbol) -4.12)

My issue is that I have no idea what that is supposed to mean, and my online homework helper simply says "Check your use of technology". Can someone walk me through what I need to do? I am absolutely lost.

And before it is mentioned or suggested, I am trying to do this problem with "homework helper" assistance to figure out the steps first. This means that once I have completed it, the problem will be refreshed and all values will be randomly generated again into a new problem. So assistance will not give me an easy answer. I truly just need to know what to do next. Thank you.
