df = 17 - 1 = 16
a) P(T > 2.120)
= 1 - P(T < 2.120)
= 1 - 0.9750
= 0.0250
b) P(T < 1.337) = 0.9000
c) P(T < -1.746) = 0.0500
d) P(T > 2.583)
= 1 - P(T < 2.583)
= 1 - 0.9900
= 0.0100
e) P(-2.120 < T < 2.120)
= P(T < 2.120) - P(T < -2.120)
= 0.9750 - 0.0250
= 0.9500
f) P(-1.746 < T < 1.746)
= P(T < 1.746) - P(T < -1.746)
= 0.9500 - 0.0500
= 0.9000
