Question

State whether the null hypothesis should be rejected on the basis of given P-value. P-value 0.002, a 0.01, one-tailed test.

Answer 1

The decision rule is, reject the null hypothesis if $p-value\lt \alpha$.

For this case, $p-value=0.002$ and $\alpha=0.01$.

Since $p-value=0.002\lt \alpha=0.01,$ we reject the null hypothesis.

Therefore, the decision is to reject the null hypothesis.
