Question
Three different assembly methods have been
proposed for a new product. A experimental design
was chosen to determine which assembly methods
results in the greatest number of parts produced per
hour, and 30 workers were randomly selected and
assigned to use one of the proposed methods. The
number of units produced by each worker follows.

3. If SST=4256, SSTR=420 , Set up the ANOVA
table and use a=0.05 to test whether the mean
number of parts produced is the same with each
method.
