Response:
1.) Subjects = 18 aquariums, each containing mussels
2.) Factors (levels) = temperature (3 levels) and salinity (2 levels)
3.) Treatments include: High salinity at high temperature; High salinity at low temperature; High salinity at medium temperature; Low salinity at low temperature; Low salinity at high temperature; Low salinity at medium temperature.
4.) Response variable = size of mussel produced
5.) Implementing random assignment minimizes the risk of bias and confounding variables.
6.) For replication purposes, every one of the six treatments could be applied to 3 tanks, thus having 3 aquariums designated for each treatment.
7.) This arrangement might introduce a potential location-based effect that could skew the results of our study, thus resulting in a false relationship.
8.) A control experiment with no salt added is not viable since mussels require salt for survival.
Step-by-step explanation:
Responses are explanatory.
