Births are approximately Uniformly distributed between the 52 weeks of the year. They can be said to follow a Uniform distribution from 1 to 53 (a spread of 52 weeks). Round answers to 4 decimal places when possible.

1. The mean of this distribution is
2. The standard deviation is
3. The probability that a person will be born at the exact moment that week 11 begins is P(x = 11) =
4. The probability that a person will be born between weeks 19 and 38 is P(19
5. The probability that a person will be born after week 28 is P(x > 28) =
6. P(x > 7 | x < 20) =
7. Find the 65th percentile.
8. Find the minimum for the upper quartile.
