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?
Homework Answers
Yes they can be, i dont have Stata. I have solved them manually.
e)
dof in part (c) is high so it is approximately acting as standard
normal distribution.
