    I feel like im in a huge mess because I have to calculate a student t test manually to prove I understand. Im currently on the access course and never came into contact with formulas. I just don’t understand how to calculate it. If anyone could give me a simple step by step approach I would really appreciate it.
    The assignment is about the difference between mean of heart rate and the breathing rate, they both were conducted on 8 different subjects and the duration of intensity was 1,2,3,4,5 minutes. I already calculated the standard deviation for each subject’s mean but that’s it.  I would very much appreciate your help!
Do you agree with the PM's proposal to cut tuition fees for some courses?
