Consider the data with analysis shown in the following computer output: Level N Mean StDev A 4 10.600 2.561 B 5 16.800 2.168 C 6 10.800 2.387 Source DF SS MS F P Groups 2 123.32 6166 11.05 0.002 Error 12 66.97 5 Total 14 190.29 What is the pooled standard deviation? What degrees of freedom are used in doing inferences for these means and differences in means? Round your answer for the pooled standard deviation to two decimal places. The pooled standard deviation is i degrees of freedom - The absolute tolerance is + 0.01. For standard deviation, an exact #, no tolerance for degrees of freedom
