John gets a weekly allowance of $20 from his parents. The only thing he has a real interest in buying is a big slice of pizza af
ter school for $2 per slice. Below shows his marginal utility for each life consumed (see image).
a) What is the optimal quantity of pizza slices for John to buy? Explain. (For now, completely ignore the funnel cake column).
b) If John purchased 8 slices, what total utility would he enjoy?
c) The school starts selling funnel cakes for $4, which John discovers offers the marginal utility per cake shown on the same table. Complete a table that shows the marginal utility per dollar for each slice of pizza and each funnel cake (separate columns).
d) Assuming John’s parents do not allow him to use any savings, what is his optimal consumption bundle of pizza and funnel cakes? Explain.
e) At John’s optimal consumption bundle, what total utility will he gain?

Graph is attached.
Answer:
a) The number of children who took extra candy can be said to be the operational definition of the dependent variable here.
(The dependent variable is defined as the variable that is tested by the experimenter. The outcome of dependent variable depends on the independent variable).
b) The psychologist hypotheses are :
H1 : The children would take more candy when they were alone.
H2: The children would take more candy when they were masked.
The data does not in anyway support the hypothesis 1 of the psychologist because from the graph the percentage of children who took candy when alone was low.
The data fully supports the hypothesis 2. From the graph we could denote the percentage of children who colected additional candy when masked was higher.
c) The findings cannot be generalized to all children because only children from the psychologist's neighborhood was used in the experiment.
d) This study is not a naturalistic behaviour because the psychologist is manipulating a variable. Therefore we cannot call this study a naturalistic behaviour.
e) Modeling: Here the children's behaviour may be influenced because they may try to imitate what other children did. A child may take additional candy because another chid took additional candy.
Deindividuation: In this case, the children may feel a loss of identity or anonymous because they are in group. They may take extra candy because they feel anonymous.
From the graph, we could see the percentage of children in group who took extra candy was higher than the percentage of chidren alone who took extra candy.
Lawrence Kohlberg’s preconventional stage: A child's behaviour may be influenced by his self interest to gain reward. This may make the child not collect extra candy.
This Lawrence Kohlberg’s preconventional stage may also influence the behaviour of the children as the children may also be afraid of punishment, which may result in them not collecting extra candy
