We are testing to see if the mean hemoglobin level among a group of pregnant women is more than 12 gm/dl, which is the population mean. We have created a 95% confidence interval of 10-14 based on a sample of 100 lab results from this population. What decision will you make if the sample mean is 13.9?

• A. Reject H0 in favor of H1
• B. Fail to accept H0 in favor of H1
• C. Accept the H0 and reject the H1
• D. We cannot tell what our decision will be from the information given
