The following competing hypotheses are formulated to test whether the median difference for a matched-pairs sample differs from zero: H0: mD = 0 versus HA: mD ≠ 0. With α = 0.05 and p-value = 0.03, What is the conclusion to the test?
1) Reject H0 and conclude that the median difference significantly differs from 0.
2) Do not reject H0 and conclude that the median difference significantly differs from 0.
3) Reject H0 and conclude that the median difference does not significantly differ from 0.
4) Do not reject H0 and conclude that the median difference does not significantly differ from 0.
