30.6 Conclusions: Two independent means

In conclusion we write:

Moderate evidence exists in the sample (two independent samples \(t=2.631\); two-tailed \(P=0.011\)) that the population mean reaction time is different for students using a mobile phone (mean: 585.19 ms; \(n=32\)) and students not using a mobile phone (mean: 533.59ms; \(n = 32\); 95% CI for the difference: \(12.4\) to \(90.9\)ms longer for phone users).

Again, the conclusions contains an answer to the RQ, the evidence leading to this conclusion (\(t=2.631\); two-tailed \(P=0.011\)), and some sample summary statistics, including a CI.
