what is difference between p value and confidence interval
Answers. Best Answer: The P value relates to the Z score. The confidence interval relates to the percentage. For example with a 95% confidence interval your answer will need to be less than 5% for one tail and less than 2.5% for 2 tails to be accepted. For a P-value the significant Z-score must be more extreme than your answer to accept the statistic. Source(s): BUS205.
