Text Problems are from DeGroot and Schervish, Probability
& Statistics (3rd edn).
- Exercises
3/e § 8.8, p 525: | 2 | 3 | 4 | 10 | |
4/e § 9.8: | 2 | 3 | 4 | 10 |
- Another Problem
The random variables Xi for 1≤i≤n are independent from
the Normal distribution with uncertain mean μ but known standard
deviation σ=2.0. We wish to test the hypothesis
H0: μ=0 against alternative H1: μ=1.
- To achieve both α and β no more than 0.01,
how large a sample-size n will be needed?
- Find the minimal sample size and give the rejection region
explicitly to achieve α≤0.01 and β≤0.10.
Good Luck!
