- The probability computed in Step 4 is
compared to the significance level stated in Step 2. Since the
probability value (<0.0001) is less than the significance level of
0.05, the effect is significant.

- Since the effect is significant, the null
hypothesis is rejected. The conclusion is that the probability of graduating
from high school is greater for students who have participated in the
early childhood intervention program than for students who have not.

- The results could be described in a
report as:
The proportion of students from the early-intervention group who graduated from high school was 0.86 whereas the proportion from the control group who graduated was only 0.52. The difference in proportions is significant, z = 4.69, p < 0.001.
