9.7 Using the table for the t distributions, make an assessment for the probability of the (The answer to part (a) is provided.) (a) T>2.6 when d.f. =7. (Answer: P[T>2.6] is between .01 and .025 because 2.6 lies between t.05=2.365 T>1.9 when d.f. =16 (c) T<1.5 when d.f. =11. (d) T>1.9 when d.f. =10. (e) T<2.8 when d.f. =17..
