Final answer:
Colleen's choice to enter the 10,000-meter race despite better chances in the 100-meter race indicates an internal locus of control, showing her belief in personal effort determining outcomes. Jane's belief that her bad grade is due to her professor's dislike suggests she has an external locus of control.
Step-by-step explanation:
In Julian Rotter's theory, if Colleen believes she would have a better chance of winning the 100-meter race but decides to enter the 10,000-meter race instead, it suggests that Colleen has an internal locus of control. The choice to enter the more challenging event implies that she believes her outcomes are the result of her own efforts and decisions, rather than external factors. Colleen's decision does not necessarily reflect her expectancy for success in the 10,000-meter race; rather, it demonstrates a willingness to take on challenges and a belief in her ability to influence the outcome through her dedication and effort.
Regarding Jane's situation, if she believes that her bad grade is a result of her professor not liking her, then Jane most likely has an external locus of control. This means Jane perceives that her academic outcomes are influenced by factors beyond her control, such as the professor's personal feelings towards her, rather than her own efforts or the quality of her work.
