Answer 1

Consider the speed range of 5mph and prepare the frequency table as follows

Speed range Mean Speed (mph) 32.5 37.5 42.5 47.5 52.5 57.5 62.5 67.5 Frequency Cumulative frequency 30-35 36-40 41-45 46-50 51-55 56-60 61-65 66-70 16 27 54 76 89 96 100 27 13 4

the frequency vs speed plot is as follows of the given data

Frequency vs Speed 30 25 20 s 15 10 0 10 20 30 40 50 60 70 80 0 Speed in mph

And the Cumulative frequency vs speed plot is

Cumilative frequency vs Speed 120 100 80 60 E 40 ㄩ 20 0 0 10 20 30 40 50 60 70 80 Speed in mph
