Explanation:
Operant conditioning refers to a learning method that obtains through rewards and punishments to measure change in behavior. By operant conditioning, there is a correlation made between an action and a reason for that behavior.

Answer:
The researcher is confounding the sweetness of the cereal and the colour of the cereal.
Explanation:
Based on the results, it would be unclear if the subjects prefer the cereal because of the colour or because of the sweetness --it is only the latter the researcher wants to know about. This would be the dependent variable.
To fix this, the researcher should use the same colour for both sweetened and unsweetened cereal and have each preschooler try both. It is possible to colect data through observation (look at the children's reactions) or simply asking for their opinions at the end of the experiment.
The marginal cost is how much it costs to produce one item more. It cost 0$ to produce 0 bikes but if you make one, then it costs 80$. Hence the marginal cost for the first bike is 80$. For the fourth bike, we have that the 3 bikes cost 110$ and the 4 bikes cost 130$. Hence it costs 20$ dollars to produce one more bike (from 3rd to 4th) and hence the marginal cost is 20$. Similarly for the 6th bike, we compare the cost of producing 5 bikes to the cost of producing 6 bikes and we get that the marginal cost is 50$. Applying the same methodology, the marginal cost for the 7th bike is 60$.
