Answer:

Part A:

The cofounding variable is a factor that could cause a result on the experiment. This would be the people taking extra food.

Independent variable would be being asked to sign in or not and take free food, because independent variable is a variable that is changed or manipulated and in this case the people were split in half and the hypothesis is that the people who didn't sign in would take more food.

Operational definitions are important when conducting research because it defines all the variables in the experiment, so it can be replicated. The operational def for the dependent variable would be "Doing the right thing even though you aren't being watched"

Part B:

The data does not support the hypothesis because even the people who signed in could've taken extra food when the dean wasn't looking. The findings cannot be generalized to all students because some students could have been taught better and can differentiate between right and wrong. So the people who were not signed in could've just taken one burger and drink, and the people who were signed in might feel obligated to take more than one burger because they had signed in and didn't just come without signing in.

The study is not a naturalistic observation because the observer did not look at the people who took the food and which side took more food.

Answer:

Frequency of SS dominant individuals is $0.57$

Explanation:

The total population of rabbit is 650

Out of 650 rabbit, nearly 39 have recessive allele "s".

Hence, frequency of recessive genotype = $\frac{39}{650} = 0.06$

Frequency of recessive allele = $\sqrt{0.06}$

$q = \sqrt{0.06} = 0.245$

Frequency of dominant trait allele "S" $p = 1-q = 1-0.245 = 0.755$

Frequency of SS dominant individuals is $p^{2} = 0.755^2 = 0.57$
