A computer generates random numbers between 10 and 20 that follow a Uniform Distribution. What percentage of the numbers will be between 12 and 13?

1. A computer generates random numbers between 10 and 20 that follow a Uniform Distribution. What percentage of the numbers will be between 12 and 13?
2. In a Standard Normal Distribution (µ=0, σ=1), what z value has 15% of the area to its right?

For this and the next three questions, please assume µ=10 and σ=2.

3. What is P(8<=x<=10)?
4. What is p(8<=x<=13)?
5. What is P(x>=14)?
6. What x value has 80% of the area to its left?
