Question
A total of 171 volunteer students participated in an experiment studying the effect of guilt emotion on how a decision maker focuses on a problem, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task, students were presented with a decision problem where the stated option had predominantly negative features (e.g., spending money on repairing a very old car). The results (number responding in each category) are summarized in the accompanying table. Is there sufficient evidence (at = .10) to claim that the option choice depended on emotional state? Use the data saved to answer the question.

Two tailed chi square test
Prepare contingency table.
he Chi-square statistic, P value and statement of significance appear beneath the table. Blue means you're dealing with dependent variables; red, independent.
The chi-square statistic is 72.2338. The P-Value is < 0.00001. The result is significant at p < 0.10.
Hence the option choice is dependent of emotional state and this is statistically significant.
