Answer 1

Answer #1

Answer: 0.1767

(by using t-table or excel)

[Excel command: =TDIST(0.95,20,1)]

[We use 0.95, as the probability less than -0.95 or probability greater than 0.95 are same due to symmetry.]

[For t-table, find value corresponding to the 0.95 and degrees of freedom = 20. Select proper t-table. Some table gives upper probabilities while some gives lower.]
