  1. Urban participants reported an average of 8.9 hours of internet use per week with a standard deviation of 2.77.
  2. Suburban participants reported an average of 12.7 hours of internet use per week with a standard deviation of 4.88.
  3. Rural participants reported an average of 9.8 hours of internet use per week with a standard deviation of 2.82.

 

Using the data that was collected, the researcher found the following:

  1. The sum of squares between groups is equal to 78.86.
  2. The sum of squares within groups is equal to 354.51.
what is the obtained test statistic?  Enter your answer rounded to two decimal places (i.e., 10.01, not 10, not 10.1, not 10.001).
