There are two groups: 'Those who have a car" and "Those who do not have a car". If you were asked the question on greatest distance: In that data set (for the group you would belong to (own car/not own car)), I guess that my z-score would be about ___________. Determine what group you are in? the "car" group or the "no car" group? Then decide what YOUR distance value would be expressed as a Z score. Base this Z score on the the percentage of students in your group that you believe would have a distance value less than your value. You need to look at the 'percentile' column in Table 8.1 in the text to determine your Z score since the percentile column represents the percentage of Z values below a particular Z and this percentile then corresponds to the percentage of distance values below a particular distance value. FOR THIS EXERCISE, WE ASSUME THE DATA WILL BE NORMALLY DISTRIBUTED (BELL-SHAPED) ALTHOUGH IT ACTUALLY IS NOT, SINCE WE USE THE Z TABLE WITH NORMALLY DISTRIBUTED DATA
