Question
A paper describes a study in which 50 Greek male taxi drivers drove in a driving simulator, In the simulator, they were asked to drive folowing a lead car. On one drive. they had no distractions and the average distance between
the driver's car and the lead car was recorded. In a second drive, they were asked to drive in the simulator while sending and receiving test messages. The mean of the 50 sample differences
(no distraction - reading text messapes) was 16 meters and the standard deviation of the sample differences was 1.63 meters. The authors concluded that there was evidence to support the claim that the mean folowing
eistance for Greek taxi drivers is greater when there are no distractiens than when the driver is texting.
A USE SALT
Construct a 95 cenfidencea interval for the diference in mean following distance for Greek tani drivers while driving with no distractions and while driving and texting. (Use o dutretion - Preading test meser Round your
answers to three decimal places.)
