Question

1. Suppose T follows a t-distribution with degree of freedom 14. From t-Table, you can find the range of the probability P (T > 2.12) is:

A. (0.10, 0.15), B. (0.15, 0.20), C. (0.05, 0.10), D. (0.01, 0.025), E. (0.025, 0.05)

Answer 1

Here,

degree of freedom=14

P(T>2.12)=0.02617842

That is, 0.025 < P(T>2.12) < 0.05

option (E) is correct.
