Can I get help with parts a),b) and c)

2. Let X1,..., X10 be a random sample of n = 10 from a normal distribution N(0,02).
(a) Find a best critical region of size 0.05 for testing
Hoo21, H₁:0² = 2.
:
(b) Deduce the power of the test in part (a), that is, compute the power function K(2). Feel free to
use any computing language to help you compute the power.
(c) Find a best critical region of size 0.05 for testing
Hoo² 1, H₁ : 0² = 4.
(d) Deduce the power of the test in part (c), that is, compute the power function K(4).
(e) Find a best critical region of size 0.05 for testing
where σ > 1.
Hoo² = 1, H₁:0² = 0²,
(f) Find a uniformly most powerful test and its critical region of size 0.05 for testing
Ho: 0² = 1,
H₁:0² > 1.
