(a) The independent variable is the presence of others and it has 3 levels.
(b) The dependent variable is people's willingness to assume responsibility for the welfare of others. It is measured on a nominal scale.

(d) The critical value is 5.143.
(e) Since 21.5 > 5.143, we can reject the null hypothesis.

14) (20) Does the presence of others affect people's willingness to assume responsibility for the welfare of others? For example, does the presence of other people affect our reaction to potentially dangerous smoke seeping from a wall vent? To answer this question, a researcher measured how long in seconds) it took subjects to ask for help as smoke gradually filled a waiting room. The room was occupied by a subject plus "crowds of either zero, two, or four experimental confederates...
