These values represent the probability to the right of the given positive values.

Value	t -probability
1.00	0.1666
1.20	0.1244
1.40	0.0909

These values represent the positive t- value for a given probability in both tails (sum of both tails).

Probability	t -value
0.20	1.3406
0.10	1.7531
0.05	2.1315

(A) What is the probability of a t-value between –1.40 and +1.40?

(B) What is the probability to the left of t-value of -1.7531?
