Question

You are running a clinical trial for a new vaccine that is being developed to treat high blood pressure (hypertension) in adults aged 35 to 70 years old. 153 people sign up for the eight week long study. Group 1 consisted of 77 people who were given a placebo, while Group 2 consisted of 76 people who were given the new vaccine. After 8 weeks, 146 participants returned to have their blood pressure measured, 74 people from Group 1 and 72 people from Group 2. The additional 7 people did not return for various reasons. The systolic blood pressure results were as follows: Group 1 mean: 155 mmHg Group 2 mean: 129 mmHg Group 1 standard deviation: 9.89 Group 2 standard deviation: 17.48 The data was used to create two bee swarm box plots, where the whiskers indicate the highest and lowest data points. What information can you gather from these graphs? The minimum value of the control group is approximately 90 mmHg. The inner quartile range (IQR) of the control group is approximately 16. The Q3 value of the experimental group is approximately 118 mmHg. The difference in blood pressure between the two groups is statistically significant.
