Mid-Term MM207 Project The Mid-Term Project is worth 100 points. Please download this document to your computer and save it using the naming convention specified in the course syllabus. For the Mid-Term Project you will be using the MM207 Student Data Set, the survey codebook, and StatCrunch as necessary. You should enter your answers/responses directly after the question. There is no need to retype the project. After completing and saving the project, submit your project in the Mid-Term Drop Box. In the course, go to Unit 4 -> Instructor Graded Project -> StatCrunch to access the MM207 Student Data Set. When the page loads you will need to click on Data Set on the left side of the page. You do not need a StatCrunch ID or a password to access the data set; simply click the on Data Set to load the data file. Name: 1. In the following situation identify the implied population. A recent report on the weekly news presented the findings of a study on the effectiveness of Onglyza, along with diet and exercise, for treating diabetes. 2. In the following scenario identify the type of statistical study that was conducted. A Gallop poll surveyed 1,018 adults by telephone, and 22% of them reported that they smoked cigarettes within the past week. 3. In the following scenario what is the statistic and the parameter it would estimate. A recent study of 460 drivers age 70 and over by the National Highway Traffic Safety Administration reported that 75% of those drivers had uncorrected vision problems. 4. What type of sampling procedure was used to collect the data in the MM207 Student Data Set? 5. From the MM207 Student Data Set identify one variable that is discrete and one variable that is continuous. your Explain reasoning. How do you know? a) Discrete: b) Continuous: 6. From the MM207 Student Data Set identify the following: a) A variable measured at the nominal level of measurement. b) A variable measured at the ratio level of measurement. c) A variable measured at the ordinal level of measurement. MM207 Mid-Term Project 7. What is the approximate percentage of students represented in the data set who are between the ages of 29 and 45 inclusive? 8. Assume that you are preparing a report on MM207 statistics students at Kaplan University to present to the Kaplan Board of Trustees. Prepare an appropriate graphical representation for each of the following variables. a) The different majors of students taking MM207. b) The number of hours spent on school work by students in MM207. 9. Using the range rule of thumb estimate the standard deviation for the number of credit hours students in this sample are taking and the shoe sizes of the females in the class. Then using StatCrunch compute the actual standard deviation. Compare the results. a) Does the range rule of thumb overestimate or underestimate the standard deviation for number of credit hours? b) Does the range rule of thumb overestimate or underestimate the standard deviation for shoe sizes of females? c) How does the shape of the distribution impact what you conclude? 10. Using measures of center and measures of variability compare the number of hours on school work (Q11) and the number of hours watching television (Q14). a) Which variable has greater variability? How do you know? b) What number of hours on school work would be at the 10th percentile? c) What number of hours watching television would be at the 90th percentile?
