Assume for a given hypothesis testing problem that the test statistic was computed and led to a rejection of the null hypothesis at the .05 level of significance. Based on this information, we can further conclude that since Ho was rejected at the 5% level, it O must be accepted at the 7% level of significance. O must be rejected at the 7% level of significance. O must be rejected at the 3% level of significance. O must be accepted at the 3% level of significance.
