A psychologist studying nonverbal communication became interested in whether she and her lab assistants had begun to use more than the average amount of nonverbal gestures. During a lab presentation, she measured the amount of this type of communication in one of her assistants. She then compared this assistant's score to the average that her research had obtained. She found that her assistant was, in fact, using a significantly higher amount of nonverbal communication (Z score of 4.25, which was significant at the .01 level).

Explain this result by making explicit reference to: 1) Z scores, 2) normal curve percentages, 3) probability, and 4) sample and 5) population.
