Table 18.3 reports that the P‐value for the test for overall effect is P = 0.24.

Which, if any, of the following statements is CORRECT?

A. The result is not statistically significant.

B. The probability of getting this difference or one more extreme, when the null hypothesis (of no overall effect) is true, is 0.24.

C. The probability of getting this difference or one more extreme is 0.24.

D. There is sufficient evidence to reject the null hypothesis.

E. The individual trial results are consistent with no overall population effect.
