Answer:
1.) Subject = 18 Aquariums each with mussel
2.) Factors(levels) = temperature(3 levels) and salinity (2 levels)
3.) Treatment = High salinity high temperature ; High salinity low temperature ; High Salinity medium temperature ; Low salinity Low temperature ; Low salinity, High temperature ; Low salinity Medium temperature.
4.) Response variable = size of mussel produced
5.) Random assignment will help prevent the introduction of bias and confounding variable.
6.) For replication purpose, Each of the six treatment could be assigned to 3 tanks, so 3 aquarium for one treatment.
7.) By doing such we might be a possible location based effect which might might creep into our research. Hence, causing a spurious relationship.
8.) A control experiment whereby no salt is added will cause the mussel to die as they require salt to survive.

I'd say B. but that's only because I divided the number of times he flipped the coin by the number of sides it has, 2, and came up with 246. The closest number on here to that is 231 or B. I hope I helped.
Answer:
a) For a constant increment in x-variable, there is a constant increment in y-variable, for example, for x = 0 to x = 0.5 (increment = 0.5) y-variable goes from 60 to 62 (increment = 2); the same is valid for any couple of (x,y) values. This behaviour is characteristic of linear equations.
b) slope:
m = (increment in y-variable)/(increment in x-variable) = 2/0.5 = 4
y-intercept:
y1 = m*x1 + h
60 = 4*0 + h
60 = h
equation: y = 4x + 60
where y represents scores and x represents hours spent studying
c) The slope indicates that you need to study 1 hour to increase your score in 4 points
The y-intercept indicates that you will get at least a score of 60, even though you hadn't studied
Hello,
Answer A: no solutions
y-5x=4
and y-5x=-3
==>4=-3 ==> no solutions
