Concept explainers
Use the information given in the previous exercise to construct and interpret a 95% confidence interval for the difference in
11.30 The paper referenced in the previous exercise also had the 50 taxi drivers drive in the simulator while sending and receiving text messages. The mean of the 50 sample differences (no distraction – reading text messages) was 1.3 meters and the standard deviation of the sample differences was 1.54 meters. The authors concluded that there was evidence to support the claim that the mean following distance for Greek taxi drivers is greater when there are no distractions than when the driver is texting. Do you agree with this conclusion? Carry out a hypothesis test to support your answer. You can assume that this sample of 50 drivers is representative of Greek taxi drivers.
