Student t test - I need some one to help me calculate.... (Oct/01/2005 )

I would like to calculate the P value for this numbers

Group A: Mean: 94.2 SD: 9.7 n=122
Group B: Mean: 62 SD: 8.7 n=685

if you can tell me what software you used so I can do the rest on my own that would be great, I have many more results.

I do not have all the data (the computer c drive crashed and I was only able to save these results)

Thanks

Graph Pad Prism is the easiest.

Thanks I'll look it up
