A researcher is interested in studying how playing video games before bed might influence sleep quality. She randomly assigns 30 teenagers to play video games right before bed for a week, and 30 teenagers to watch TV right before bed for a week, and then compares their sleep quality.
What would be a type I error for this scenario?
What would be a type II error for this scenario?
Given that,
A researcher is interested in studying how playing video games before bed might influence sleep quality.
Here Hypothesis is would be as follows
H0:
There no difference between sleep quality of teenagers right before playing video games and watching TV before bed for a week
H1:
There difference between sleep quality of teenagers right before playing video games and watching TV right before bed for a week
Type 1 error scenario is:
Concluding that , There difference between sleep quality of teenagers right before playing video games and watching TV right before bed for a week. But, actually there is no significant difference between sleep quality of teenagers right before playing video games and watching TV right before bed for a week.
Type 2 scenario is:
Concluding that,
There no difference between sleep quality of teenagers right before playing video games and watching TV tight before bed for a week . But actually there is significant difference between sleep quality of teenagers right before playing video games and watching TV right before bed for a week.
