Dong Lee Math-138 Professor Deshpande 10-16-16 Project Part 2 Research Proposal: Introduction: The first variables I plan to study are the hours you spend on the smartphone daily and the monthly phone bill you get. The second variable I plan to study are the mileage of the car and number of visit to auto repair shop. The quantitative variables I plan to study are related to each other. First variables are related because the more you spend you time on your smartphone the more you use the data and when you use more data you pay for higher data plan which cost more on your phone bills. Second quantitative variable are related because the higher mileage cars have more problems mechanically and got to get it fixed and go to auto repair shops. I think the hours you spend on the smartphone and number of mileage of the car might cause a change in the other variables. I think my research is important and interesting because you could find out the relationship between variables and it could help you lower your phone bills and know the average mileage of the cars. Methods: I am intended to gather my data in three groups. First I am going to ask students in the classroom after class. Second I am going to ask co-workers at the work on break time. Lastly I whill ask my friends by calling or texting them anytime during the day. There is no ethical issue I have to anticipate with my research. Materials: First Survey Question \"How many hours do you spend on your smartphone?\" \"How much monthly phone bills do you get?\" Second Survey Question \"How many miles do you drive per year?\" \"How many times did you visit to auto repair shop over the past year?\" Data: Hours Spent of your phone (24 hours) Student 1 Student 2 Student 3 Student 4 Student 5 co-worker 1 co-worker 2 co-worker 3 co-worker 4 co-worker 5 Friedn 1 Friedn 2 Friedn 3 Friedn 4 Friedn 5 Friedn 6 Friedn 7 Monthly Phone Bill 3.5 5 2.5 3.5 5 8 75 85 50 70 80 110 5 85 4 75 4 80 4.5 80 3 2.5 5 4 6 7 6 60 55 75 75 80 85 85 Friedn 8 Friedn 9 Friedn 10 Student 1 Student 2 Student 3 Student 4 Student 5 co-worker 1 co-worker 2 co-worker 3 co-worker 4 co-worker 5 Friedn 1 Friedn 2 Friedn 3 Friedn 4 Friedn 5 Friedn 6 Friedn 7 Friedn 8 Friedn 9 Friedn 10 4.5 8 8 Miles you drive per Visit to autorepair shop per year year 5800 15000 13800 7500 20000 20500 70 90 100 2 4 4 2 5 6 9600 3 14600 4 13000 3 6000 2 20500 31000 8000 11000 17000 7400 12500 18600 13400 17600 4 8 3 4 5 2 4 5 3 4 Distribution of Quantitative Data: Z-Scores and the Normal Distribution: Linear Regression and Correlation Scatterplot: Correlation Coefficient and Linear Regression: Discussion: Technology Considerations: Column1 Hours Spent of your phone (24 hours) Monthly Phone Bill Student 1 3.5 Student 2 5 Student 3 2.5 Student 4 3.5 Student 5 5 co-worker 1 8 co-worker 2 5 co-worker 3 4 co-worker 4 4 co-worker 5 4.5 Friedn 1 3 Friedn 2 2.5 Friedn 3 5 Friedn 4 4 Friedn 5 6 Friedn 6 7 Friedn 7 6 Friedn 8 4.5 Friedn 9 8 Friedn 10 8 75 85 50 70 80 110 85 75 80 80 60 55 75 75 80 85 85 70 90 100 Student 1 Student 2 Student 3 Student 4 Student 5 co-worker 1 co-worker 2 co-worker 3 co-worker 4 co-worker 5 Friedn 1 Friedn 2 Friedn 3 Friedn 4 Friedn 5 Friedn 6 Friedn 7 Friedn 8 Friedn 9 Friedn 10 Miles you drive per yearVisit to autorepair shop per year 5800 2 15000 4 13800 4 7500 2 20000 5 20500 6 9600 3 14600 4 13000 3 6000 2 20500 4 31000 8 8000 3 11000 4 17000 5 7400 2 12500 4 18600 5 13400 3 17600 4
