Joe has learned how to use in R, but hasn’t really bothered to learn much about statistics. He measures 1) gender (male or female), 2) GPA, 3) number of close friends, 4) number of hours worked a week, and 5) dollar amount of student loans. He uses R to calculate bivariate correlations between all 5 measures (Pearson’s r). He is excited to discover a number of interesting correlations. You need to break some bad news to him, however: some of his ‘findings’ don’t make any sense. Which of Joe’s results is an improper use of statistics? (a)For number of close friends and hours worked a week, Pearson’s r = -0.65 (b)For GPA and amount of student loans, Pearson’s r = -0.75 (c)For GPA and number of close friends, Pearson’s r = 0.60 (d)For amount of student loans and hours worked a week, Pearson’s r = 0.90 (e)For gender and hours worked a week, Pearson’s r = 0.80

O Both Felipe and Susan scored higher than the median. O Susan answered 16 more questions correctly than Felipe. O Felipe's and Susan's scores were both in the bottom half of all scores. (b) Which of the following must be true about Felipe's score? O Felipe scored lower than about 73% of the students who took the exam. O Felipe got about 73% of the questions corect. O Felipe scored higher than about 73% of the students who took the exam. O Felipe got about 73% of the questions wrong.
