1, 4 & 6 are likely to be correct
Explanation:
1 When the target group is American adults, who very often have landline telephones and cellphones, it can be argued that including them will be more accurate.
4 This may be true; I can imagine that there are people, socioeconomically different, who don´t have (access to) landline phones.
6. Birthday doesn´t have anything to do with age, as suggested in nr. 5 and nr. 7. Birthyear does. The selection of most recent birthday in a household is a good way of selecting at random.
2, 3 and 8 are statements that don´t have any scientifical reasoning.

Answer:
Gender pay gap.
Explanation:
One of the problems that Feminism has shown is that inexplicably men and women aren't paid the same amount of money for doing the same job. Resourch proved that women in higher positions also get paid less than the men that there are in lower positions. In that sense, boss women are paid less than worker men.
This difference is often justified for women who participate in part-time jobs and have long absences (due to pregnancy and the cares towards the baby). But this isn't the case for all women. So what are the reasons for this difference, when men and women are working the same and have the same experience? There are many since not hiring women for the maternity leave or paying them less for this, gender stereotypes (that usually is sutil) and the direct discrimination (and when this happen, is easier to report).
In the chart, from 2009, we can see the median weekly earnings of full-time wage and salary workers, by sex, race, and ethnicity. This demonstrate that not only for being women get paid less but it can also be for their ethnicity.
In conclusion, this is a problem that isn't resolved and is been studied with many perspectives to see if this is just another type of discrimination against women.
