This paper studies the two-factors design model when the heteroscedasticity of variance is present in errors. As can be observed, testing of hypothesis based on the main effects for this design model can be performed using Hotelling's T2 test. Simultaneous confidence intervals are also proposed. Finally, the proposed methodology is applied to a real-life example.

The aim of this literature review paper is to show the negative consequences of globalization via the mass media, especially the internet, on student sexual abuse, to provide analyses of children’s rights and their shortcomings in this arena in urban areas, and to offer some solutions to reducing student vulnerability. The limitations of the research are based on insufficient information in the case of sexual abuse due to cultural issues in different states, which mean that not all cases of abuse by parents, teachers and the authorities are reported, so it is impossible to adduce complete data on victims of student sexual abuse. We shall attempt to show the growing danger of sexual abuse for students that poses a threat to future generations due to one of the major aspects of globalization—the internet—by taking into account diverse cultural communities and their dynamic limitations and political and social structures. This paper studies the different laws on child sexual abuse in some countries and some of the national and international organizations that support children’s rights. It shall also define the increasing sexual abuse of students and their access to the internet.
