Final answer:
A confidence interval that passes zero, even when p-value is significant, may indicate that our results are statistically meaningful.
Step-by-step explanation:
A confidence interval that passes zero, even when p-value is significant, may indicate that our results are statistically meaningful.
When constructing a confidence interval, if the interval includes zero, it suggests that the population parameter is not significantly different from zero. This means that the result is not statistically meaningful or significant, regardless of the p-value being significant.
On the other hand, if the confidence interval does not include zero, it indicates that the population parameter is significantly different from zero, making the result statistically meaningful and significant.
