A hypothesis test is to be performed to test the equality of two population means. The sample sizes are large and the samples are independent. A 95% confidence interval for the difference between the population means is (1.4, 8.7). If the hypothesis test is based on the same samples, which of the following do you know for sure: Group of answer choices The null hypothesis would not be rejected at the 5% of level of significance. The null hypothesis would not be rejected at the 2.5% of level of significance. The null hypothesis would be rejected at the 2.5% of level of significance. The null hypothesis would be rejected at the 5% of level of significance.
