Calculates the cumulative distribution function between two values.
The cumulative normal distribution function between x1 and x2.
A baseball shall weigh not less than five nor more than 5 1/4 ounces avoirdupois.
If a shipment has an mean of 5.1 oz and standard deviation of .05 oz, what percent are within the specifications
|5||x1||5.0000||Stores the x1 value.|
|5.25||x2||5.2500||Stores the x2 value.|
|5.1||μ||5.100||Stores the mn (mean) value.|
|.05||σ||0.0500||Stores the sd (standard deviation) value.|
|cdf||0.9759||Calculates the cumulative normal distribution between x1 and x2.|
So, about 97.6%
What would 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||0.0428||Calculates the sd value.|
