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$.
The correct answer is this - <span>this research would not require IRB review because it would be eligible for exemption since the researcher is not interacting with the children and the playground is a public setting.
If the conditions were a little bit different, then his IRB review would also require different results. However, since there is no real interaction with the children, but rather only observation, an IRB review is not necessary in this case and can be avoided.
