A recent experiment conducted at University.r of Utah used a sample of college studenm to investigate whether cell phone use impairs drivers' reaction times. On a machine that simulated driving situations, at irregular periods a target ashed red or green. Participants were instructed to press a brake button as soon as possible when they detected a red light. Under the cell phone condition, the student carried out a conversation about a political issue on the cell phone with someone in a separate room. In the control conditionI theyr listened to a radio broadcast or to hooksontape while performing the simulated driving. For each student, for a particular condition the outcome recorded in the table on slide 17 is their mean response time (in milliseconds] over several trials. Research question: Is there a difference in the mean reaction times of students who underwent the two conditions, one using the cellphone and the other not using the cellphone? Hint: You will need to use input the data into Excel to obtain the pertinent statistics. You can either use Method 1 or Method 2 introduced in Lecture 3. Perform the hypothesis testing and write up the results. Then, paste the Excel output {do NOT attach the excel file). Eell Phone?
