Question

Please help with D and E

Three professors at George Washington University did an experiment to determine if economists are more selfish than other people. They dropped 64 stamped, addressed envelopes with $10 cash in different classrooms on the George Washington campus. 44% were returned overall. From the economics classes 56% of the envelopes were returned. From the business, psychology, and history classes 31% were returned.

• R = money returned
• E = economics classes
• O = other classes

O Part (d)
Is money being returned independent of the class? Explain.
Money being returned is independent of the class because the probabilities do not overlap.
Money being returned is independent of the class because the probability that one class returns the envelope does not affect the probability of another class returning the envelope.
Money being returned is not independent of the class because 0.56 x 0.31 + 0.44.
Money being returned is not independent of the class because the probability that money is returned is affected by which class it is dropped in.
O Part (e)
Based upon this study, do you think that economists are more selfish than other people? Explain.
Economists are not more selfish than other people because they returned 56% of the 64 envelopes that were dropped.
Economists are not more selfish than other people because the economics class returned 56% of the envelopes in their classes.
Economists are not more selfish than other people because everyone is selfish.
Economists are just as selfish as other people because only 44% of the people returned envelopes.
