Q

How to use Z = (X - µ)/σ

Oh yea possible simultaneous eqns for these btw

A
  1. Find Z first
  2. Plug in and get ur stuff

Q

If “area” is less than, what it means for mean and σ during inverse/Z = (X - µ)/σ

A
  • Area stays the same as stated
  • µ = 0
  • σ = 1
    Plug in the formula

Q

If “area” is greater than, what it means for µ and σ during inverse/ Z = (X - µ)/σ

A
  • Area is 1 - [stated]
  • µ = 1
  • σ = 0
    Plug in the formula
