feelings impact on-the-job decisions. In one experiment, 57 participants were assigned to a guilty state through a reading/writing task. Immediately after the task, the participants were presented with a decision problem where the stated option had predominantly negative features (e.g., spending money on repairing a very old car). Of these 57 participants, 45 chose the stated option. Suppose 10 of the 57 guilty-state participants are selected at random. Define x as the number in the sample of 10 who chose the stated option. a. Find P(x = 5). b. Find P(x = 8). c. What is the expected value (mean) of x?

Transcribed Image Text:4.78 GUILT IN DECISION MAKING. The Journal of Behavioral
Decision Making (January 2007) published a study of how guilty
feelings impact on-the-job decisions. In one experiment, 57
participants were assigned to a guilty state through a
reading/writing task. Immediately after the task, the participants
were presented with a decision problem where the stated option
had predominantly negative features (e.g., spending money on
repairing a very old car). Of these 57 participants, 45 chose the
stated option. Suppose 10 of the 57 guilty-state participants are
selected at random. Define x as the number in the sample of 10
who chose the stated option.
a. Find P(x = 5).
b. Find P(x = 8).
c. What is the expected value (mean) of x?
