1 Mitchell Myers Professor Pilkington MATH 10140

2 Project Type: A The following question was sent in an to all males in Keough 2B: Please choose one of the following as the sport you most enjoy watching on television: Football Basketball Baseball Tennis Hockey Other

3 Non-response: This bias was expected, but it was acceptable because the question was sent to the entire population of interest. A large enough portion of the population responded to give an appropriate sample. Selection: This was not a problem because the question was sent to the entire population of interest. Measurement error: This was assumed to not be a problem because my tallying skills are competent.

4 n = 30 Football – 10 Basketball – 4 Baseball – 3 Tennis – 2 Hockey – 4 Other – 8

5 p = proportion of interest in the sample n = 30 For football: 0 p-3 σ < p+3 σ (0.086) < (0.086) <

6 n = 30 p = proportion of interest in the sample Football: p = I am 80% confident that the proportion of males in Keough 2B who enjoy watching football on television more than any other sport is between and Tennis: p = I am 99.9% confident that the proportion of males in Keough 2B who enjoy watching tennis on television more than any other sport is between (essentially 0) and Other: p = I am 60% confident that the proportion of males in Keough 2B who enjoy watching a sport other than football, basketball, baseball, tennis, or hockey most on television is between and

9 No problematic biases arose. The results met my expectations in that football received the most votes. Some people did not answer the but sufficient participation numbers were met after a door to door survey of those who did not answer the . A change I would have made is excluding less popular sports like tennis from the choices and adding more popular sports like soccer.

10 Mean: A mean could not be found from this experiment because no matter how the numbers were distributed, the mean would remain 5. Median: 4 Mode: 4 Standard deviation: The standard deviation from the assumed mean of 5 was 2.5.

11 The experiment was a success and told me what kind of sports my 2B friends enjoy watching on television. I might redo this project with an open ended question allowing all sports as an answer in order to get numbers for a wider variety of sports. Because of random rooming, this experiment could most likely be applied to at least all males at Notre Dame, which shows why football is such a popular sport at our school.
