Somebody wants to describe the relationship between grade point average (GPA) and time spent using a search engine to find information on the web.Time spent using a search engine is measured in the survey by asking a random sample of 100 students to choose one of the following answers: four or more hours every day, 2- 4 hours every day, less than 2 hours every day, 4 to 6 days a week, less than 4 days per week.

1. Which variable is a continuous variable and which is a categorical variable?
2. How would one describe the distribution of the continuous variable?Why would someone make that choice?That is, what statistics or graph or table would be produced? If it is a graph, what is on the Y-axis and what is on the X-axis?If it is atable, what does the table show?
3. How would one describe the distribution of the categorical variable?Why would that choice be made?That is, what statistics or graph or table would one produce? If stated graph, what is on the Y-axis and what is on the X-axis?If stated table, what does the table show?
4. How would one describe the relationship between the two variables?Bespecific.
5. A regression is run to quantify the effect of time spent using a search engine on GPA.What is the dependent variable?What are the independent variables?What other 'control' variables will be included?Choose at least two other control variables and explain why they would be included in the regression.
6. What is a hypothesis about the effect of time spent using a search engine on GPA? Write down a null and an alternative hypothesis.Explain why that alternative was chosen.
