(Use i = 6) 96 69 63 69 70 76 39 82 95 88 57 77 88 43 55 94 73 66 69 98 84 81 82 71 77 90 76 86 59 63 71 85 49 93 92 72 68 73 89 75 79 90 74 75 78 60 48 90 64 69 2. On the first day of class last school year, 30 students were asked for their one-way travel time from home to school (to the nearest 5 minutes). The resulting data were as follows: (Use eight class) 20 25 35 30 25 20 40 20 15 25 15 20 20 40 50 20 20 25 25 30 25 25 20 20 15 20 15 25

Tally Lowest score: 71 Class Interval Frequency (f) Highest score: 99 i = 3 71-73 74- 76 III 3 77-79 I3D Since the lowest score is 71 then the lower limit of first class interval will start at 71. 80-82 9. Thus, 83 - 85 Lower limit: 71 86-88 6.
