Hi everyone, new to the forum.
I was helping a friend with this problem for her online course. I did a 2 sample Ttest on a TI84 Plus and I don't understand why it's not working. On the screenshot the 1.594 is supposed to be the correct answer, and the 1.657 is the answer I put. I am also posting screenshots of what I did on the TI84. Any help would be appreciated.
Thanks,
Tom
