The research question is important to a researcher as it helps in solving the issue that the researcher wants to solve.
- The research topic will be "Social media has an effect on the behavior of children".
- The research question will be "what effect does social media has on the effects of the behavior of children".
- The null hypothesis will be "there is no statistical significance between social media and children's behavior".
- The alternative hypothesis will be "there is a statistical significance between social media and children's behavior".
- The null hypothesis will be rejected when the p-value is equal to the significance level or it's less than it.

Answer:
672
Step-by-step explanation:
If there must be at least 4 people in each group, then the number of people in the group for tennis must be 4, 5, or 6.
There are
(10/k)=(10!)/(k!(10−k)!)
ways of choosing k people from a group of 10, and so there are
(10/4)+(10/5)+(10/6)=(10!)/(4!6!)+(10!)/(5!5!)+(10!)/(6!4!)
=2×(10×9×8×7)/(4×3×2×1)+(10×9×8×7×6)/(5×4×3×2×1)
=2×(10×3×1×7)/(1×1×1×1)+(1×3×2×7×6)/(1×1×1×1×1) =420+252=672
Answer:
(9, 6)
