Question 1

As you know, in order to graduate from a University, you need to have a minimum GPA of 2.0. Surely, you think to yourself, students must do better than 2.0. After all, almost everyone you know has a 3.0 GPA. You decide to do some research. You sample a representative and random group of 856 current University undergraduate students, and ask them their overall GPA. You then set out to do your statistical analysis to see if the average GPA of students is 3.0.

What is the sample:

What is the population:

Is it descriptive or inferential

What are the level(s) of measurement:

What are the independent & dependent variable(s) (if any):

What is the statistical analysis of this question:

Question 2

A campus student art council proposes to exhibit the work of a controversial artist known for his violent and sexual depictions of religious figures. The campus administration will allow the council to exhibit the work only if the council can demonstrate that the student body is in support of it. In addition, the campus administration would like to see how current students and alumni differ in their support of the exhibit in a visual format. The council surveys all current students and alumni and asks them whether they support or oppose the exhibit. Then, the council conducts their statistical analysis and presents their findings to the campus administration.

Question 3

A professor who teaches a section of an English course required of all first-year students has a hunch that, on average, students who attended private high schools are better prepared in English than students who attended public high schools. The professor decides to test her hypothesis. She generates a random and representative sample of 538 current first-year students at her college. She asks each student whether they had attended a private or public high school, and also administered a test covering grammar and vocabulary (an index score ranging from 0 to 100). Now, she sets to work and conducts her statistical analysis.
