<PRE><B>Question 322458</B>
A study compared testosterone levels among athletes in four sports: soccer, track, Lacrosse, and water polo. 
The total sample size was n =30 (10 soccer, 10 track, 5 Lacrosse, and 5 water polo). 
A one-way analysis of variance was used to compare the population mean levels for the four sports. The sum of squared errors is SS Error = 100. What is the value of the Mean Square Error (MS Error)?
-----
MS(error) = SS(error)/(N-k) where N = # of values in all samples = 30
and k = # of means being compared = 4
----
MS(error) = 100/(30-4) = 100/26 = 3.85
