A professor is conducting research on memory. She shows her subjects (volunteers from her Intro Psych course) a list of words on the computer, with some of the words being food items and the rest of the words being completely unrelated. She then gives each subject 30 seconds to recall as many words from the list as possible, with her theory being that the subjects will be able to remember the food-related words better than the unrelated words. Listed below are the scores representing the number of food-related and nonfood-related words that each subject was able to recall:

.
Test the null hypothesis of no significant difference between the number of food-related and nonfood-related words that the subjects could remember. What do your results indicate?
