Make a simulation to verify the following theorem: if X1 ∼ N(µ1,
(σ 1)^2 ), X2 ∼ N(µ2, (σ2)^ 2 ), and X1 and X2 are independent,
then X1 + X2 ∼ N(µ1 + µ2, (σ2)^2+ (σ 2 )^2 ).

1. When σ is unknown and the sample is of size
n ≥ 30, there are two methods for computing confidence
intervals for μ.
Method 1: Use the Student's t distribution with
d.f. = n − 1.
This is the method used in the text. It is widely employed in
statistical studies. Also, most statistical software packages use
this method.
Method 2: When n ≥ 30, use the sample standard
deviation s as an estimate for σ, and then use...
