A researcher is interested in the relationship between concussions and short-term memory loss. To explore this relationship, the researcher collects data on the number of concussions and number of words recalled on a memory test. Assume SP = -34       SSconcussions =    58        SSnumber of words recalled = 27 Interpret the Pearson correlation coefficient between concussions and number of words recalled in terms of the strength and direction of the relationship:
