APFIVE Inference for Comparing Two Sample Means
In an experiment comparing two diets on blood pressure reduction, patients on the DASH diet experience an average reduction of $$7$$ mmHg (SD = $$2$$), while patients on the TLC diet see an average reduction of $$5$$ mmHg (SD = $$2.5$$). Assuming large sample sizes, what inference is most plausible?
Blood Pressure Reduction Data:
| Diet | Mean Reduction (mmHg) | Standard Deviation |
|---|---|---|
| DASH | 7 | 2 |
| TLC | 5 | 2.5 |
Assume both groups have large sample sizes.
A
The DASH diet produces a statistically significantly greater reduction in blood pressure than the TLC diet.
B
The TLC diet produces a statistically significantly greater reduction in blood pressure than the DASH diet.
C
There is no significant difference between the two diets.
D
The results are inconclusive without further p-value analysis.
