1. The value for the t9 distribution whose upper-tail probability is 0.005, from the table, is
ANSWER is 3.250
How do you find the answer?
Look up the df=9 in the left hand side of the t-distribution table and the alpha level =0.005 along the top row. Find the intersection of the row and column.

t9 = 3.250
