Scenario: The following table 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 Sociological Research Methods class. Use the data to answer the Three questions listed below. Make sure that you summarize and report if the results were significant using the F ratio formula. Report your answers in the Computed Value Tables.
