Suppose 8 adult patients with the same diagnosis were randomly selected. Researchers want to check whether the injected medication will affect the change in body temperature. The patient's body temperature was measured before and after the injected medication and resulting data are given in the accompanying table. Construct and interpret a 95% confidence interval estimate for the difference in mean temperature before and after the injected medication.
A)The confidence interval is . You can be 95% confident that the actual difference in mean temperature before and after the injected medication for adult patients with this diagnosis is between -0.379 and -0.021.
B)The confidence interval is . You can be 95% confident that the actual difference in mean temperature before and after the injected medication for adult patients with this diagnosis is between -0.832 and 0.432.
C)The confidence interval is . You can be 95% confident that the actual difference in mean temperature before and after the injected medication for adult patients with this diagnosis is between -0.423 and 0.023.
D)The confidence interval is . You can be 95% confident that the actual difference in mean temperature before and after the injected medication for adult patients with this diagnosis is between -0.223 and 0.223.
E)The confidence interval is . You can be 95% confident that the actual difference in mean temperature before and after the injected medication for adult patients with this diagnosis is between -0.531 and 0.131.
