Marcos thought of three questions that could be randomly correlated to age. He typed a survey that asked students and teachers for their age, number of hours of sleep they get a night, number of cups of caffeinated beverages they drink in a day, and number of hours spent on their cell phones a day. We made copies and distributed them throughout the school. During our next class, Marcos will make a scatter plot of the data. He will use his graphing calculator to find the line of best fit for the data.
