Complete these problems. Write them up carefully, in the order assigned, for handing in with the rest of your homework.

• 8.9 (Hint: Mimic the discrete case on p. 337.)
• 8.10, 8.11
• 7.9
• For X ~ Norm(μ, σ²), compute E[X] from the definition of expectation. (Hint: You will probably use substitution and the fact that f_X integrates to 1.)
