The completed table for the number of text distribution including the frequency and relative frequency for teens and adult is given below.
The side-by-side graph is attached in the picture below.
Few number of texts are sent by larger percentage of adults while larger number of text are sent by a larger percentage of teens
TEENS :
Number of TEXTS __Frequency __ Relative freq
None ____________ 13 ___ 13/658 __0.020
1-10______________147 __147/658 __ 0.223
11-20 ____________ 64 __ 64/658 ___0.097
21-50 ___________ 123__ 123/658___ 0.187
51-100___________ 122__ 122/658___ 0.185
100 + ___________ 189___189/658___0.287
Total frequency of teens = (13+147+64+123+122+189) = 658
ADULT :
Number of Texts __ Frequency ___ Relative frequency
None ___________ 171 ____171/1938 = 0.088

11-20 ___________246 ___ 246/1938 = 0.127
21-50 __________ 242 ___ 242/1938 = 0.125
51-100___________131 ____ 131/1938 =0.068
100 + ___________163 ____163/1938=0.084
Total frequency of adults = (171+985+246+242+131+163) = 1938
Relative frequency = frequency / total frequency
The side - by - side relative is attached below :
From the side-by-side graph, the percentage of adults who send few text (0 - 20) are more than teens while the percentage of teens who send many text per day (21 - 100+)are more than Adults.
