Homework Answers
1) Since the 2 levels intersects so there is an interaction between the factors.
2) The 2 levels are parallel to each other and also to the horizontal axis, hence,
neither factor looks to have an effect.
3) The 2 levels are parallel to each other but are not parallel to the horizontal axis, so
both factors have an effect.

The results of a two-factor, independent-measures, equal n experiment are summarized in the following matrix. The numerical value in each cell is the mean score obtained from the sample in that treatment condition B B2 А M=4 M-2 M- Az M = 6 M-8 ME M M Compute the overall means for the scores in A, the scores in Az, the scores in B, and the scores in B2.

Investigators working on commericially cultivating shrimp are interested in determining the best conditions in which for them to grow. They are interested in knowing what impact water temperature (either 25 C, 30 C) and the salinity level (10 %, 25 % and 40 %) have on the growth of shrimp. Three replicates were used for each of the 6 possible treatment combinations. Post-larval shrimp were placed in each of the 18 tanks and fed the same amount of food. After...

The number of spruce moths found in traps after 48 hours
was recorded. The traps were placed in different locations in the
tree (top, middle, lower branches, and ground) and different types
of lures were placed in the traps (scent, sugar, chemical). Use
Minitab, R, or your preferred statistical software to
analyze the data shown below.
