Question details

Not sure how to approach these. Can they be solved using Stata?

a. If Y is distributed N(2,5), find Pr(Y>1).

b. If Y is distributed t12, find Pr(Y>2.18).

c. If Y is distributed t60, find Pr(-1.67≤Y≤1.67).

d. If Y is distributed N(0,1), find Pr(-1.67≤Y≤1.67).

e. Why are the answers to (c) and (d) approximately the same?
