Normal Probability

Your Discussion Posting:  If X ~ N (750, 12), we can determine the P(x > 784) as follows:

 μ = 750

 σ = 12

 x = 784

 Z = x − μ σ

 Z = 784 −750 12

 Z =2.8333...

 Z = 2.83

 P ( X > 784 ) = 1 − 0.9977

 P ( X > 784 ) = 0.0023

So, the probability of an observation greater than 784 with a standard deviation of 12 is 0.0023.

 -------------------------------------------------------------------------------------------------------------

Determine the P (x > 784) for each of the following two scenarios:

X ~ N (750, 24)doubling

 X ~ N (750, 6)halving 

For each scenario(1)  (2)X ~ N (750, 12)

• The Show-Your-Work process P(x > 784)
•  given value(s) appropriate symbol(s)
•  with symbols only
• with numbers plugged in
• Unrounded 
• Rounded 
• A normal curve with the following:
•  area of interest shaded
•  labeled
• meansaxes
• X X
• ZZ
• AAA
• A detailed explanation of how the change in the standard deviation does or does not affect each of the following:
• center
• spread
• shape
• P(x > 784)

I got the first part but having trouble with X~N(750,6)
