Question: Bandura, Blanchard, and Ritter (1969) conducted an experiment that provided individuals with one of four treatments for their intense fear of snakes. One group worked with a model - a person who handled a 4-foot king snake and encouraged others to imitate her. One group watched a film of adults and children who enjoyed progressively closer contact with a king snake. A third group received desensitization therapy, and a fourth group served as a control, receiving no treatment. The numbers of snake-approach responses after treatment are listed in the table. A higher number of snake-approach responses indicates that the individual was willing to approach a snake more often.

Perform a hypothesis test to determine if there is a significant difference between the groups in the number of snake-approach responses.  Show all necessary components of a full hypothesis test, including a source table.
