A large pharmacy chain examines medication adherence across 60,000 patients over one year. Treatment group (n = 30,000) receives weekly reminder texts; control group (n = 30,000) receives no reminders. Results: treatment group adherence = 64.2%, control group adherence = 63.1%. The difference is statistically significant (p = 0.008). The annual cost of the text reminder program is $250,000. Which statement most accurately describes the relationship between statistical and practical significance?
