Answer 1

Answer:

$H_{0}$ : Pa - Pt = 0

 $H_{1}$ :Pa - Pt ≠ 0

• Pa is the proportion of Adults
• Pt is the proportion of Teen

If she wants to know that whether there is a significant difference between the proportion of teens and adults that check social media at least once per day, we must form the scenarios in 2 days:

 $H_{1}$ :Pa - Pt ≠ 0
