( ) ≈ 62.73° ( to the nearest hundredth )
Very likely...... I assume
Answer:
This study is an experiment
The response variable is the level of reaction (how excited they were) of the two groups after seeing their various shows and the explanatory variable are the two shows that was manipulated by the researchers.
Step-by-step explanation:
An observational study is a study where researchers collect data based on what is seen and heard and conclude based on the data collected. The researcher has no control over the variables, while an experiment is a method of applying treatments to a group and recording the effects of such treatments.
This study is an experiment because the researchers had control over the variables by manipulating the variables: showing Episode 1 of Season 8 to half of them and showing Episode 1 of Season 1 of a new comedy show to the other half. The response variable is the level of reaction (how excited they were) of the two groups after seeing their various shows and the explanatory variable are the two shows that was manipulated by the researchers.
