QUESTION 2 A sample is used to obtain a 95% confidence interval for the mean of a population. The confidence interval goes from 10.89 to 13.21. If the same sample had been used to test Ho: H= 12 vs. H1:µ# 12, then you would conclude from this test that the Ho hypothesis can be rejected at the 5% significance level. O True O False
