## 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.
