You have an srs of size 22 and calculate the one-sample t statistic. what is the critical value t∗ such that (a) t has probability 0.05 to the right of t∗? (b) t has probability 0.8 to the left of t∗?

(a)  1.721   (b) -0.859074

Step-by-step explanation:

Given : Sample size : n=22

Degree of freedom =

Significance level :

(a) By using t-test distribution table, the critical value for  t has probability 0.05 to the right of t:-

(b) Similarly, for t has probability 0.8 to the left of t :-

111
