The null hypothesis looks plausible for which of the following p-values of a test of significance?

1.43%
2.27%
3.43 of 1%
A1 & 2 only ✓ Correct
B2 & 3 only
C1 & 3 only
D1, 2 & 3
Correct answer: (A) 1 & 2 only
Explanation

A null hypothesis looks plausible when the p-value is large, meaning weak evidence against it.

A p-value of 43 percent is large, and the null remains plausible.

A p-value of 0.27 percent is tiny and gives strong grounds to reject the null.

The value 0.43 of one percent equals about 0.43 percent, again very small.

Both small p-values point to rejecting rather than retaining the null.

Only a high p-value leaves the null hypothesis credible.
