Researchers identified 2587 10th grade students in the Los Angeles area who did not have significant symptoms of ADHD(Attention-Deficit/Hyperactivity Disorder). These students were followed for approximately two years. The frequency withwhich each student used digital media over the two-year period was recorded. At the end of the two-year period, students wereagain tested for symptoms of ADHD. Researchers found that the higher the frequency of digital media use, the more likely thestudent was to have developed symptoms of ADHD at the end of the study.What are the explanatory and response variables?ResponseExplanatoryAnswer Bankthe two-year perioddigital media usage2587 10th grade studentsADHDno symptoms of ADHD at the beginning of the study

A cognitive psychologist conducted a study of whether familiarity of words (X) predicts the time it takes (in seconds) to press a button indicating whether the word is singular or plural (Y), with all participants being given the same words. Familiarity with these words was rated at a later time on a 7-point scale (with higher numbers indicating more familiarity). The participants' scores were: X : 6, 2, 5 ,3 ,7 Y : 0.3 , 1.5 , 0.8 , 1.4 ,0.1 a.Figure the correlation coefficient Describe the correlation Figure the linear prediction rule; list the b value, a value and the final formula Predict the time it takes to press a button if the familiarity with the word is 1
