A school tested a new study‑prep app by having each student take a practice exam before and after using the app for two weeks. The researchers computed the paired differences (After – Before) and constructed a 99% t‑confidence interval for μ_diff, obtaining (2.4, 7.1) points. Interpret this interval. With 95% confidence, the researcher concludes that the [word2] mean score improvement due to the study app is between 2.4 and 7.1 points, meaning students scored [word3] after using the app.
