3. An AP Stats student designs an experiment to see whether today's high school students are becoming too calculator-dependent. She prepares two quizzes, both if which contain 40 questions that are best done using paper-and-pencil methods. A random sample of 30 students participates in the experiment. Each student takes both quizzes--one with a calculator and one without--in a random order. To analyze the data, the student constructs a scatterplot that shows the linear association between the number of correct answers with and without a calculator for the 30 students. A least-squares regression yields the equation: Calculator (predicted) = -1.2 + 0.865(Pencil) r= 0.79 Which is greater, the standard deviation of the number of correct answers on the paper-and-pencil quizzes or the standard deviation of the number of correct answers on calculator quizzes?
