The work you have told me to do is finished. The result can be shown as follow.
1. As for the summary of Smartphone Users’ monthly bills. The data vary impressively from each other. The biggest number goes to 350 and the smallest one goes to 13. But we can still see that the average money people pay should be 55.
From the histogram provided in the appendix, you can see clearly the numbers of users for each interval of monthly bills. The two intervals: 46-60 and 61-75 have the highest value, which means that most users expensed 46-75 $ last month.
2. As for Prepaid and Postpaid plan. In the sample people who used PostPaid plan are more than those who used PrePaid plan. Speaking of average the former is larger than the latter, which means PostPaid plan charged more than PrePaid. PrePaid plan's sample variance is much bigger than that of PrePaid plan's, which means the former charged more fluctuated than the latter.
3. As for the summary of the most frequently download entertainment content. In the sample people mostly used smartphones for videos; the number is 45, then ringtones 23, music 21, games 18, other 17, wallpapers 14. They used for screensavers least. The number is 7.
4. As for the current user satisfaction with their providers.
a. Users are generally satisfied. Very Satisfied accounts for 42% and Moderately Satisfied accounts for 33%. They accounts for about three quarters of all the samples. Little Dissatisfied accounts for 18% and Very Dissatisfied accounts for 7%. They accounts less than the former two.
