Determine the critical t-scores for each of the conditions below. a) one-tail test, alphaequals0.05, and nequals20 b) one-tail test, alphaequals0.005, and nequals39 c) two-tail test, alphaequals0.10, and nequals11 d) two-tail test, alphaequals0.02, and nequals16

a) 1.729, b) 2.712, c) 3.169, d) 2.602.

Step-by-step explanation:

Since we have given that

a) one-tail test, alpha = 0.05, and n = 20

So, the degree of freedom =

So,

b) one-tail test, alpha = 0.005, and n = 39

So, the degree of freedom =

So,

c) two-tail test, alpha = 0.10, and n = 11

So, the degree of freedom =

So,

d) two-tail test, alpha = 0.02, and n = 16

So, the degree of freedom =

So,

Hence, a) 1.729, b) 2.712, c) 3.169, d) 2.602.
