Topic 6 Discussion 2
A research firm tracks the average highway speed
of 30 drivers driving home on Day 1. For the next 10 days, the drivers are
given two cups of coffee 1 hour before the drive home. On the 10th day, the
average highway speed is measured again. Does this study involve dependent or
independent samples? You are interested in knowing if there is a statistical
difference in driving speeds between Day 1 and Day 10. Which statistical test
would be appropriate? Why?
