Suppose you have computed the following 95% confidence interval for a population mean y from a set of data: (8.56, 11.44). You want to conduct the following hypothesis test using the same data at significance level a = 0.05. HO: H= 12 vs. H 1: µ#12 What conclusion can you draw? O A. As the interval does not contain 12, we reject the null hypothesis. O B. As the interval does not contain 12, we fail to reject the null hypothesis. O C. No conclusion can be drawn since there is no relationship between a confidence interval and a hypothesis test.

QUESTION 8 Suppose you have computed the following 95% confidence interval for a population mean u from a set of data: (8.56, 11.44). You want to conduct the following hypothesis test using the same data at significance level a = 0.05. Ho: H= 12 vs. H 1: p # 12 What conclusion can you draw? O A. As the interval does not contain 12, we reject the null hypothesis. O B. As the interval does not contain 12, we fail to reject the null hypothesis. O C. No conclusion can be drawn since there is no relationship between a confidence interval and a hypothesis test. O D. Not enough information to choose between the two hypotheses.
