Question:

You want 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.

Which variable is a continuous variable and which is a categorical variable?

How would you describe the distribution of the continuous variable? Why did you make that choice? That is, what statistics or graph or table would you produce? If you state graph, what is on the Y-axis and what is on the X-axis? If you state table, what does the table show?

How would you describe the distribution of the categorical variable? Why did you make that choice? That is, what statistics or graph or table would you produce? If you state graph, what is on the Y-axis and what is on the X-axis? If you state table, what does the table show?

How would you describe the relationship between the two variables? Be specific.

You decide to run a regression 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 you include? Choose at least two other control variables and explain why you would include them in the regression.

What is your hypothesis about the effect of time spent using a search engine on GPA? Write down a null and an alternative hypothesis. Explain why you chose the alternative that you did.

All production costs have been steadily rising in the Donner Company for several periods. The company maintains large work in process inventories. Donner Company's cost per equivalent unit computed using the FIFO method would be the same as that computed under the weighted-average method. higher than that computed under the weighted-average method. lower than that computed under the weighted-average method. could be lower than, the same as, or higher than that computed under the weighted-average method.Question 3 Oriole Corporation had 288,000 shares of common stock outstanding on January 1, 2017.
