I need help with these two. For letter b, this is what I did:
1-0.99 = 0.01
t0.01= 2.764 (The problem is using the symmetry -t, in this case maybe the answer is negative?)
For no. 2: using t-table 2.807 = t0.005
0.945 +0.005 = 0.95
1-0.95 = 0.05
t0.05 = 1.714 (IDK if this should be negative, plus I'm not really sure with the process, I do not think it's complete)
Thanks!
