a fraction of my thesis 。would you like to help me correct possible errors？ thanks！ In the case of equal number of bandwidth can be obtained, the user is more willing to provide elementary privacy ,followed by the second , and finally the third degree of privacy.At the same time,in the case of providing the same level of privacy ,the reduction of the ratio of users who are willing to provide privacy corresponds with the reduction of the bandwidth .When the number of bandwidth exceeds a certain value,(10MB/s,for example),more than the half of users would sacrifice their second and third privacy for the use rights of high -speed broadband regardless of the possible risk of offering them.The behavior shows that the pleasure of getting the access of internet beats its rival, the potential risk of providing private information. Otherwise,when the number of bandwidth is prior to a certain value,(like 0.1MB/S) ，despite the tiny worries of users about the first degree privacy , 61.67% of them are unwilling to provide them to obtain a low -bandwidth .So we can not keep away from the truth to claim that the users’reluctance indicates that it is’t worth doing that. In summary,whether these users would shake his head or no when are required to sacrifice their privacy is not only related with the importance of them, but also the reciprocation of exposing them.Conclusion of the survey taken in mind,the validity of mock data is demonstrated,thus ,on the whole ,coincides the previous analysis of the model established before and the very model does agree with the real life.
