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?
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.

Please complete the above question using STATA software. I am not sure what you mean when you said you cannot complete it in the space provided- only a log file is needed. 5) Simulate data according to the following. Please provide a log ile and any supporting exhibits x = 12 ,50 e N(0,1) a) Provide an estimate of the coefficients in y + + є b) Are Bi,B2 "near" the true values? c) Store the coefficients in a matrix...

An equation in the form with is called a Bernoulli equation and it can be solved using the substitution which transforms the Bernoulli equation into the following first order linear equation for : Given the Bernoulli equation we have so . We obtain the equation . Solving the resulting first order linear equation for we obtain the general solution (with arbitrary constant ) given by Then transforming back into the variables and and using the initial condition to find ....
