Calculates the 2 tail cumulative normal distribution function.
The 2 tail cumulative normal distribution function.
A baseball shall weigh not less than five nor more than 5 1/4 ounces avoirdupois.
If a shipment has an mn of 5 1/8 oz and sd of .1 oz, what percent are within the specifications
|5.25||x||5.2500||Stores the x value.|
|5.125||μ||5.1250||Stores the mn (mean) value.|
|.1||σ||0.1000||Stores the sd (standard deviation) value.|
|cdf||0.7887||Calculates the cumulative distribution between -x and +x.|
So, about 75%
What should the standard deviation of be so that 99% are within the specifications?
These keystrokes assume the values from example 1.
|.99||cdf||.9900||Stores the cdf value.|
|σ||0.0485||Calculates the sd value.|
