A researcher has developed a new drug designed to reduce blood pressure. In an experiment, 21 subjects were assigned randomly to the treatment group and received the new experimental drug. The other 23 subjects were assigned to the control group and received a standard, well‑known treatment. After a suitable period, the reduction in blood pressure for each subject was recorded. A summary of these data is: ¯ Treatment group (new drug) 21 23.48 8.01 Control group (old drug) 23 18.52 7.15 A 95% confidence interval for the difference in reduction of blood pressure between these two drugs, using Option 2 and the conservative method for degrees of freedom is:
