The estimated mean difference in SBP values at end of the intervention for the Individualized treatment group compared to the Standard treatment cohort is 10 mmHg, with a 95% confidence of (5.3 mmHg, 14.7 mmHg). Which of the following is true about this 95% confidence interval?

a. This is a trick question: a confidence interval cannot be estimated using the results from only a single study.

b. For most (95%) studies of the same size, intervals constructed in the same way will include the value of the study mean difference ( < >) comparing the two study sample means.

c. This interval will definitely include the value of the true population mean difference.

d. For most (95%) studies of the same size, intervals constructed in the same way will include the value of the true population mean difference for the two populations being compared via the two samples.
