Please help me with all parts of this question. And explain
You create a TV program that you believe will decrease violence among teenagers. You want to test
this belief in a scientific manner, you start by obtaining a random sample of 90 teens from the local
high school. Each teen is run in both the experimental and control condition.
Experimental Condition: Watch TV program for a period of 3 months and record number of violent
acts within those 3 months.
Control Condition: Do not watch TV program for a period of 3 months and record number of
violent acts within those.
What would be your null and alternative hypotheses mathematically?
O HO: mu z 45; H1; mu < 45
O HO: mu s 45; H1; mu > 45
O HO: mu s 90; H1: mu > 90
O HO: mu - 90; H1; mu 90
O HO: mu - 45; H1; mu 45
O HO: mu z 90; H1: mu< 90

A TV program is believed to cause violence among teenagers. You want to test this belief in a
scientific manner, you start by obtaining a random sample of 100 teens from the local high school.
Each teen is run in both the experimental and control condition.
Experimental Condition: Watch TV program for a period of 3 months and record number of violent
acts within those 3 months.
Control Condition: Do not watch TV program for a period of 3 months and record number of
violent acts within those 3 months.
What are the null and alternative hypotheses stated mathematically?
O HO: mu s 100; H1: mu > 100
O HO: mu s 0; H1: mu > 0
O HO: mu s 50; H1: mu > 50
O HO: mu-50; H1: mu 50
O HO: mu < 100; H1: mu 2 100
O HO: mu = 0; H1: mu - 0
