Find the critical t values in the following cases: a. n = 4, = 0.05 (two-tailed

Find the critical t values in the following cases:
a. n = 4, α = 0.05 (two-tailed test)
b. n = 4, α = 0.05 (one-tailed test)
c. n = 14, α = 0.01 (two-tailed test)
d. n = 14, α = 0.01 (one-tailed test)
e. n = 60, α = 0.05 (two-tailed test)
f. n = 200, α = 0.05 (two-tailed test)
