Re: Exercise [21.15]
I solved it moreorless similarly.
The essential differences were only that I used the results of Exercise [21.11] to first transform my integral, and that I used the fact that the area under a normal distribution is 1, rather than using the result of Exercise [12.10] (but that amounts to the same thing).
However, neither of us have used the results of Exercise [21.13] or [21.14] in our solutions, as the question asked us to do.
Does anyone have any idea how this might be solved using the results of Exercise [21.13] and [21.14]? (because I don't!)
