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
Value | Keystrokes | Display | Description |
---|---|---|---|
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.
Value | Keystrokes | Display | Description |
---|---|---|---|
.99 | cdf | .9900 | Stores the cdf value. |
σ | 0.0428 | Calculates the sd value. |
