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: n x S Treatment group (new drug) 21 23.48 8.01 Control group (old drug) 23 18.52 7.15 The P-value for a two-sampler test using these data, using Option 2 for degrees of freedom, is: larger than 0.05. between 0.02 and 0.025. between 0.025 and 0.05. between 0.04 and 0.05.
