1.  P(µ - σ < x < µ + σ)  ≈  _______%
   
   
   
2.  P(µ < x < µ + σ)  ≈  _______%
   
   
   
3.  P(µ - σ < x < µ)  ≈  _______%
   
   
   
   
   
4.  P(µ < x < µ + 2σ)  ≈  _______%
   
   
   
   
   
5.  P(x < µ - 2σ)  ≈  _______%
   
   
   
   
   
6.  P(x > µ - 2σ)  ≈  _______%
   
   
   
   
   
7.  P(x < µ + 3σ)  ≈  _______%
