For the following study, indicate whether it is an observational study or an experiment. Explain your reasoning. If it is an obs

ervational study, give the population and the sample. If it is an experiment, give the explanatory variable and the response variable.
Just prior to Episode 1 of Games of Thrones Season 8, a research company randomly divided 1,000 of HBO subscribers and showed Episode 1 of Season 8 to half of them and showed Episode 1 of Season 1 of a new comedy show to the other half. They then asked everyone how excited they were about the final episode of Game of Thrones Season 8. They found that the group who saw Episode 1 of Game of Thrones Season 8 was more excited than those who saw Episode 1 of Season 1 of the new comedy show.

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.

Write a short statement that expresses a possible relationship between the variables. Gas mileage of car, cost of driving 500 mi
PIT_PIT [208]

Answer:

D) As the gas mileage increases, the cost of driving a fixed distance increases.

Step-by-step explanation:

Hello!

Given the variables

X₁: Gas mileage of a car

X₂: Cost of driving 500 miles

Normally the variable that changes more is the gas mileage of the car, depending on the type of the car or the age of different cars from the same model and brand, the amount of gas used to cover a fixed distance varies.

From a logical point of view you'd expect that the more gas the car consumes, the more it will cost to drive a fixed distance. So the correct option is D)

Options:

A) As the gas mileage increases, the cost of driving a fixed distance decreases.

B) As the cost of driving a fixed distance increases, the gas mileage decreases.

C) As the cost of driving a fixed distance decreases, the gas mileage increases.

D) As the gas mileage increases, the cost of driving a fixed distance increases.

I hope this helps!

Tems11 [23]

Answer:

Explanatory variable: Extra support by faculties

Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.

Confounding Variable: Ability of students to get passing grades.

It is an experiment to check if the hypothesis is true.

Step-by-step explanation:

An explanatory variable is a type of independent variable. An explanatory variable is that variable that explains changes in another variable. It can be anything that might affect the response variable. The explanatory variable is used to predict or explain differences in the response variable. In an experimental or research study, the explanatory variable is the variable that is manipulated by the researcher.

From the information given,

Explanatory variable: Extra support by faculties.

The response variable is also known as the dependent/outcome variable. Here, its value can be predicted or its variation can be explained by the explanatory variable. In an experimental study, this is the outcome that is measured after manipulation of the explanatory variable

From the question above,

Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.

A confounding variable is that outside influence that changes the effect of a dependent and independent variable. This extraneous influence is often used to influence the outcome of an experimental design. The Confounding Variable in the above is:

Confounding Variable: Ability of students to get passing grades.

It is an experiment to check if the hypothesis is true.
