esearch Study: The following data collected lists the typing speed as measured by a standard typing test for 12 college students, along with the number of pages they had to type for their project.
Instructions: Use the data collected to compute the values listed in Table#1. Use .05 significance. Each correct answer is worth one point. Hint: follow the steps reviewed in your Chapter 14 videos, formulas, F ratio Table and activity sheet.
