Which of the following accurately describes the p-value?

A. The square root of the p-value can be expressed as the margin of error.
B. The inverse of the square root of the p-value can be expressed as the margin of error.
C. When the p-value is less than the significance level, the results are statistically significant.
D. When the p-value is greater than the significance level, the results are statistically significant.

Answer 1

The option that accurately describes the p-value is:
C. When the p-value is less than the significance level, the results are statistically significant.
A small p-value normally at ≤ 0.05 denotes strong evidence against the null hypothesis, so you reject the null hypothesis.
