The following are the yeilds in kilograms of abovegroundbiom

The following are the yeilds in kilograms of above-groundbiomass per plot that resulted when four levels of nitrogen wereapplied to young douglas fir seedlings:

   Treatment          #0            #1            #2            #3      

                           4.37         7.5            7.8          9.4

                           6.72         8.8            7.82         9.28

                           8.32         8.73          9.62

                           8.03                          9.00

calculate 95% confidence limits for the mean of treatment#2

Solution

Answer

One-way ANOVA: valuesversus treatment

Source       DF      SS      MS       F         P
treatment     3      10.25    3.42     2.32     0.143
Error           9      13.24    1.47
Total          12      23.49

S = 1.213  R-Sq = 43.63%   R-Sq(adj) = 24.85%
