Probstat/week8 practice 2
- This is part of probstat.
To compute the cdf of standard normal random variable, you can use a table from wikipedia.
Basic practice
Let Z be a standard normal random variable (whose mean is 0 and variance is 1).
1. Find P{ Z >= 0 }.
2. Find P{ Z >= 0.5 }.
3. Find P{ Z >= 1 }.
4. Find P{ Z >= -0.3 }.
5. Find P{ -1 <= Z <= 0.1 }.
6. Find P{ Z <= 0.2 }
7. Approximate the minimum value a such that P{ Z >= a } <= 0.1.
8. Approximate the minimum value a such that P{ -a <= Z <= a } >= 0.7.
