Oregon Health Experiment Data: Finding Another ATE

Now let's check the treatment effect on diastolic blood pressure values bp_var_inp across our treatment and control groups. Once again, we'll use a t-test to measure statistical significance, and assume a p-value of less than .05 is statistically significant.

Instructions

  • 1) Run a t.test to determine if the treatment and control groups have significantly different average values for diastolic blood pressure (bp_dar_inp).
  • 2) After looking at the p-value of the t-test, can we say the t-test results are statistically significant? Answer "Yes" or "No".
