Data was collected for 384 randomly selected 10 minute intervals. For each ten-minute interval, the number of people entering the atrium of a large mall were recorded. The data is summarized in the histogram below. 20406080Number of People in 10 min140145150155160165Frequency[Graphs generated by this script: setBorder(54,40,20,5); initPicture(135.5,165,0,98);axes(1000,20,1,1000,20); fill="blue"; textabs([165,0],"Number of People in 10 min","above");line([140,-1.96],[140,1.96]); text([140,0],"140","below");line([145,-1.96],[145,1.96]); text([145,0],"145","below");line([150,-1.96],[150,1.96]); text([150,0],"150","below");line([155,-1.96],[155,1.96]); text([155,0],"155","below");line([160,-1.96],[160,1.96]); text([160,0],"160","below");line([165,-1.96],[165,1.96]); text([165,0],"165","below");textabs([0,115],"Frequency","right",90);rect([140,0],[145,83]);rect([145,0],[150,98]);rect([150,0],[155,66]);rect([155,0],[160,61]);rect([160,0],[165,76]);] What is the class width for this histogram (and corresponding GFDT)?
