NORMAL DISTRIBUTION (exclusively exckusive) Flashcards
1
Q
X~N (µ, σ2)
A
U know how it is
2
Q
Formula to find mean/standard deviation?
A
Z = (X - µ)/σ
3
Q
How to use Z = (X - µ)/σ
Oh yea possible simultaneous eqns for these btw
A
- Find Z first
- Plug in and get ur stuff
4
Q
Layout for finding µ or σ?
What can this also apply to?
A
Area: ?
µ: ?
σ: ?
Inverse normal as well
5
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
6
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
7
Q
I rest for this particular case.
A
