**Research Scenario: The Relationship Between Musicians and Music Types on Audience Applause** A researcher aimed to explore how two musicians and the types of music they perform affect audience applause. The study involved two musicians, Erica and Susan, each performing a ten-minute musical piece. Participants were randomly assigned to listen to either Erica or Susan, and to either classical or hard rock music. The volume of applause (measured in decibels) was recorded after each performance. **Means for Each Condition:** - **Classical Music** - Erica: 6.77 - Susan: 9.54 - *Overall Classical Music:* 8.15 - **Hard Rock** - Erica: 5.92 - Susan: 6.23 - *Overall Hard Rock:* 6.08 - **Musicians Overall** - *Erica Overall:* 6.35 - *Susan Overall:* 7.88 **Note:** "Overall" refers to the total average for each condition. Please use these values when describing your main effects.

I am to do a project for an inferential statistics class and I would like some basic guidance.  I am to propose a research question. My proposed research question is "Does drinking stimulants such as coffee improve a student's grades?" My population will be the students at my school. I will use a  test of association hypothesis test because I will need to find an association between drinking stimulant’s such as coffee and the grades of the students. So, I will divide the students that do drink coffee before school and those who don’t and determine if there is a sizeable difference in academic success between the two groups.   My question is what type of graph do you think would be best served to visually display the data?

A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?

Lan says that students’ favorite restaurants in Conway are not equally distributed between ZaZa’s, Umami, Mike’s Place, Brick and Forge, and The Pasta Grill. Nynaeve tests this claim by asking 40 students what their favorite restaurant is. Her survey results are 12 for ZaZa, 6 for Umami, 3 for Mike’s Place, 8 for Brick and Forge, and 11 for The Pasta Grill. Test the validity of Lan’s claim with a significance level of α = 0.05. [Hint: You are testing whether your data is a good fit against the presumption that all are equal.]
