6 (for 2–PropZTest...) |
 |
2. Input number of successes in SAMPLE1, x1 |
enter value for x1, then ENTER |
 |
3. Input number of observations in SAMPLE1, n1 |
enter value for n1, then ENTER |
 |
4. Input number of successes in SAMPLE2, x2 |
enter value for x2, then ENTER |
 |
5. Input number of observations in SAMPLE2, n2 |
enter value for n2, then ENTER |
 |
6. Select appropriate test |
use right and left arrow keys to move cursor to appropriate test, then ENTER |
 |
7. Calculate P–value |
once, then ENTER |
 |
8. Scroll down to find more calculations |
Press  |

In this case, the test was Ha: p1 < p1;
the two–sample z statistic is –2.47; the p–value is 0.00675; etc. |
9. Draw the test |
repeat steps 1 through 6 (the data should already be stored!), then
once, then ENTER |
