Blood Pressure Source

Question 34:

A new blood pressure treatment is being tested. The regression analysis below describes the relationship between the 41 test subjects’ diastolic blood pressure and the dummy variable “medication.” When a test subject is taking the new drug, the value of medication is 1, when not, the value of medication is 0.

Which of the following can be inferred from the regression analysis?

Blood Pressure Source

The medication has no statistically significant effect (at a 0.01 significance level).

The use of medication accounts for around 42% of the variation in diastolic blood pressure.
On average, test subjects taking the medication report a diastolic blood pressure level about 5 points lower than those

not taking the medication. None of the above.
