The estimated mean difference in SBP values at the start of surgery (0 minutes on the time line) for the Individualized treatment group compared to the Standard treatment cohort is 5 mmHg. The p-value from the corresponding two-sample t-test comparing the mean systolic blood pressures (SBP) at the population levels is 0.09. What is the interpretation of this p-value?

a. There is a 9% chance the null hypothesis is true.

b. If there is a population mean SBP difference in between the 2 groups, then the chances of getting a study mean difference of 5 mmHg (or something even "more extreme") is 0.09 (9%).

c. If the mean difference in SBP between the two groups is 5 mmHg cm at the population level, then the chances that this study detects this difference is 0.09. (9%)

d. If there is no population mean difference in SBP between the 2 groups, then the chances of getting a study mean difference of 5 mmHg (or something even "more extreme") is 0.09 (9%).
