Z-Test for 1 μ known σ
| Value | Keystroke | Display | Description |
|---|---|---|---|
| 6 | n | 6.000 | Stores the n value. |
| 299 | x̄ | 299.0 | Stores the x̄ value. |
| 3 | σ | 3.000 | Stores the σ value. |
| 300 | μ0 | 300.0 | Stores the μ0 value. |
| z0 | -0.8165 | Calculates the Z-Test |
This calculator also calculates the p values for the >, <, and
≠ hypothesis and
enters them in the stack.
By returning these values to the stack you can use them for other
calculations without having to write them down and re-enter them.
